Used Space vs. File Size

Q: Used Space vs. File Size

Hello TechGuys.
This is my first thread in this forum. So, i apologize if I disobey any posting rules.

After googling it for a while, I decided that I will get an answer to my question in this forum. My case is: Used Space vs. File Size
My System (c:) partition has a capacity of 15.9GB and 8.70GB of it is used. (Refer to image)

However, when I check the properties of the files on C: it shows that, 7.81GB.
So, 8.7-7.8=0.9 almost 1GB of my Hard Disk Space is lost.
(I enabled the protected and hidden files as visible)

I previously encountered the case that this difference was up to 2GB


Preferred Solution: Used Space vs. File Size

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello again,

I've got a question about this, since it seems kind of too much of a difference. I got an SSD disk of 60gb with my windows installation and few software. The disk today shows 3gb free space, (out of total 55.8) but the size of all it's folders inside (including hidden ones is 43). There is a difference of 10 GB somewhere. I've read that windows reserve 5-10% of the disk for something (not sure if it's true), but still it doesn't explain the difference. I've ran disk cleanup to free space, nothing changed. This is becoming annoying since if it keeps up, the disk will be full extremely soon.

Thank you for taking the time to read my query.
I just restored a bkf file and the restored folder is smaller than the original bkf file. I need to delete the bkf file which is 12 GB but don't want to until I am sure all the files were restored.
I would like to figure out which files were not restored.
Is there any way to figure out which files are missing. After I restored the files, the report says that hardlinks could not be transferred but does not the size of them. The bkf file size is 33,754,314 bytes larger than the restored file,but the bkf file "size on disk"is 19, 099,648 bytes smaller than the restored folder!!!
When I left click on the bkf file and select properties it does not tell me how many files are in the bkf file only the bytes.

Is there any freeware/program that will tell me the number of files in the bkf properties dialogue box? Or even better let me look at the size and number of files in the three main folders I backed up.? I can not access/explore the bkf file only restore it. That would solve my problem. My backup tree is C:sharedhardlinkdata>beth>documents and settings>beth> and then 3 folders underneath
Thank you

After doing a lot of file management (backups, deletion of unnecessary files, defrag, etc) I was able to recover a substantial amount of space. When opening up Computer, I noticed that the size was only registering about 70GB free (out of 500). Knowing this couldn't be the case (I had found the directory my screen recorder saves to, apparently it records lossless avi at 1gb/minute) I did the usual right click on all the folders in root:\ and the size count was only 162GB, with hidden and system folders viewable. I found TweakNow PowerPack 10, which I had used for its Disk Usage Analyzer. That came up with only 94GB used.

After those installs, the disk size jumped to 94GB free.

Attached is the Systweak file structure (only root:\*, so nothing personally identifiable), the [email protected] Hard Disk diagnostic (can't make much sense of it, I'm a computer guy but not that far into the really specific components), and the main Computer window and properties.

If you can make any sense of it, please let me know. Also, if you might need any other readings, just ask.

I have MS Access 2010 & have a database that has been about 45 MB in size for 2 years. About a month ago I noticed it now is 67 MB. I compact & repair every time I save it which is twice a month. I've gone back & did a compact & repair on the 67 MB file but it does not change.

I must have looked at & changed something without realizing it. The actual number of records appears to be correct. How can examine and/or compare tables or other internals between the two sizes? I've seen a program called AccdbMerge come up on a few Google hits & was wondering if anyone ever used it?

And & all suggestions would be appreciated.

A:Access file size increased in size by 50%

The only reason I've seen for a database to get very large is when there is a picture (JPG file) used in a form. Apparently Access does not do a very good job with storing this type of data. Perhaps your database has an image stored as a data item in a table (or some other place.) Other than that...no idea why you should see such a large size.

Alternately, you can create a new empty database and then copy each object from your current database to the new one, one at a time, and check the size of the new database after each copy. That will at least identify which object is causing the problem.

 I have a computer that has their "c: drive" almost full (221 gb drive). Every time it boots a message comes up saying "Windows created a temporary paging file on your computer because of a problem that occurred with your paging file configuration when you started your computer. The total paging file size for all disk drives may be somewhat larger than the size you specified." So first I tried adjusting the Virtual Memory BUT, I only have a drive C and a previous drive that is no longer there. So I am not for sure what drive to set my virtual memory to because there is not enough space on C drive with it being almost completely full and the one drive is non-existent. I am sure its a easy fix and im missing a step but i appreciate the help guys   Thanks!

As per instruction on the link below, I have modified registry to increase page file size.

I have put each 5,000 MB so page file size should be around 15 GB according to me. But when I look at "performance" tab, it shows limit only 3765392 so around 3766 MB.

I checked under settings >> Performance Options of Advance computer properties, there it shows Total Paging Size 2046 MB. But when I click change, there it contains custom size of 5,000 MB.

Using Windows XP Pro. When I right-click on the c drive and look at the pie chart information, it shows that I have 114gb of used disk space and 30gb available. This is totally not right. Here is what is weird. When I double-click the c drive and select all of the folders to see how much space they take up it tells me that the total is 30 gb not 114gb. It's like the nubmers are backwards on the pie chart info. I do have hidden files shown as well so it is not that I don't think. Any ideas?

I was just curious, does the size you specify for allocated system restoration space have anything to do with the Windows boot menu option for reverting to a previous time when settings worked?

I am curious how that works since you do not actually get a restore time selection unless you actually successfully boot up into Windows.


A:Size of allocated system restore space?

Um what?

Actually I was asking if the amount of system restore space you chose has any relation to the "last known good configuration" in the XP boot menu.

For instance, will XP have a better chance of finding a last known good configuration if you have system restore set to a larger portion of the harddrive?

I am not sure if the "last known good configuration" option has anything to do with system restore or not....

I know there isnt a way to decrease the size of spaces, but is there anyway to increase the size of a space after its been made. I have 2 spaces in a pool with the following drives:

1) Backup (no resiliency)

3 tb

2) Storage (mirror)

3 tb
650 gb
200 gb
The first space "backup" doesn't have enough large drives to be fully effective in mirroring. I only need about 850 gb to 1.5 tb of mirroring (have an extra drive that I can add later once everything is setup). The rest of the space I'd like to use without any parity or mirror, just storage of movies, etc (ideally the remaining 3 tb along with the unused 3 tb drive). I couldn't find any way to add drives to a particular space just to the total storage pool. Any way to make this work so I use the hard drives efficiently?

Also, how do you increase the size of a space after its been created? I first made "backup" with the drives in "storage" space. When adding the unused 3 tb drive, there was no option to increase size of the "backup". I wish there windows just showed me the actual size of the spaces instead of theoritcal.

Why is it that the computer does not show the full amount of space available on a hard drive that is empty?

For example, I have an 80gb drive and it said that I have 76.69gb available even when there was nothing on it! My 60gb drive says 57.27 is available. And when I partition them the partition sizes add up to those numbers. Where does the extra space go and why so much?

Also....when I partitioned it asked me what size I wanted my clusters...64k, 32k, 16k, 8k, 4k, etc. Now I understand that the smaller cluster size means less wasted space when files are saved but what is an optimum size or does it matter?

When I right click a file to view it's properties there are two different values shown: one for file "size" and the other for "size on disk". The second value is always larger. Could someone please explain what the difference is because I'm in the process of allocating space for backed up user data on a network share and I need to multiply the average file size by the number of users to get an estimate of how much space to allocate to that share. Thanks in advance!

A:file size vs size on disk

Disks are laid out at a base level in sectors, and then in clusters which are groups of sectors.
For example, on a 32GB partition (Fat32) the cluster size is 32000 bytes. On a NTFS system, the standard size is 4K.

Files can only be on a cluster boundary. Therefore, in this example, a file that is 16,000 bytes (file size) will be 32,768 bytes (on disk). And a 40,000 byte file (file size) will be 65,536 bytes (on disk).
Or, on a NTFS system, a 5,000 byte file will take 2 clusters, or 8,192 bytes (on disk)

Do Start > Run > Command and at the prompt enter

After it runs, the "xxxx bytes in each allocation unit" is the cluster size.

I tried to check how much space is there in C and it indicates only 2.9 GB is free of 50 GB C. but when I enter C drive and select all the folders and files, and click on properties, it shows total size of files on disk is 43 GB. so then I should be having free space of ~ 7 GB.

Now where the extra space go ? I dont understand this. And I enabled to view all the hidden files and folders, . Can someone help me out ?

A:C Drive shows less space than total size of all files

When windows downloads updates it creates restore points which is stored on the c drive. You might have made some your self at one time or another, these wouldn't show up because they are hidden. To clear these out you need to go in to control and then system. Click advanced settings and then click the system protection tab. You can clear out the restore points from there but keep in mind that you won't have any restore points so if anything goes wrong you won't have a restore point to go back to.

I did a system restore on my computer due to a driver misbehaving that was not allowing me to boot at the normal speed. After the restore, I attempted to delete some files that I had previously deleted because I needed to make some space on that drive. Before the deletion I had 24.6 gigabytes of free space on a drive that contained 57 gigs of info. Now when I go to my computer and click on the C: icon in order to assess the statistics, I notice that the amount of free space has changed to 53.3 gigabytes of info. However, all the programs and some of the data I had originally are all in place.

Can someone show me or give me a hint as to what happened and how to restore this disk to the original amount of free space.

Here are my specs:
Soyo Mobo PX400Ultra
Zenith Data systems CRT monitor
560 Watts Thermaltake Power supply
GEforce MX400 video card
Audigy 2 sound card
Primary IDE is c: 57 gigabytes HDD (the one that shows the difference in free space)
Secondary IDE Lite-On DVD RW drive
Terciary IDE: RAID 0 array containing 2 60 Gigs HDDs configured as G:
Thermaltake wireless keyboard and mouse
USB devices and LAN have been disabled in the BIOS

I did run Spybot and corrected a few problems.

I'm trying to summarize here. I Googled this topic and found bits and pieces about how to do it, but not all together at once.

Original Q & A:

Q: "I have system restore set with an unbound upper limit, is this going to cause any problems later?"

A: "It depends on whether you need the hard drive space that you set for it as it fills up. As the space you set fills up, older restore points will automatically be deleted to make room for the new ones, so you shouldn't have a problem at all."

Now, as for viewing or changing the allocated HD space for System Restore Points, the only thing I can find is doing it via command prompt.

I won't go into what the command prompt is or anything because anybody who is worried about the size of System Restore Points probably knows their way around the command prompt and the Registry as well.

Anyway, to sum it up:

At the command prompt (Admin), to see the currently allocated space type: vssadmin list ShadowStorage

As in:
C:\Windows\System32>vssadmin list ShadowStorage

You will get an output like this:
Used Shadow Copy Storage space: 1.291GB
Allocated Shadow Copy Storage space: 1.563GB
Maximum Shadow Copy Storage space: 11.25GB

Sizes you see listed as well as sizes you can enter are in KB, MB, GB, TB, and up.

As you can see, 1.29GB is currently in use on my system.

To change the amount of used HD space: (increase or decrease)

vssadmin Resize /For=C: /On=C: /MaxSize=4GB

Change the drive letters to ... Read more

My hard disk space is being wrongly calculated by my computer, and I would like to know why. The total amount of space (if I click on disk defragmenter) is 27.94 GB. I have noticed that over the last few months, I seem to be "losing" 1 MB per day without installing any new programs or saving stuff to the hard disk. Today, for instance, it indicated 15.09 GB - and when I turned on the PC again - also today, an hour later - it indicated 15.06 GB (which is what it is still indicating). I have not downloaded anything which could have lost me that amount of space. There is no bug or malware around either - I had my logs checked. My computer runs under Windows XP Home Service Pack 2 and IE 7. It's going to be four years old next month. Is this age-related? Is there any way to find out the TRUE size of my hard disk? Format is NTFS, by the way.

When I'm nearing the threshold of adequate free disk space for reasonable defragmentation times, I start to monitor my disk space utilization a bit more closely.

Sometimes I notice some strange changes in how much free disk space I have, meaning fluctuations in amounts as high has 3 to 4 gigabytes. For example, I will see I've got 21.6Gb free then suddenly notice it has dropped to 17.9Gb. I use the Disk Clean utility to flush any excess files out, but that doesn't do much. I check the temp folders manually, just to be sure there aren't large garbage files left behind either. I clear the cache of my two main browers. Still no change. I'll go run Windows Update, expecting that maybe some files were downloaded and are now waiting to be installed, but that doesn't turn up much either. I even reboot to see if that forces some kind of clean-up (which sometimes happens), but that may not free up any disk space.

Later on, I'll check again, and sure enough I'm back up above 20Gb in free space. A mystery, as I've no clue as to what changed. Does anyone have an idea as to what may account for such large amounts of disk space being mysteriously occupied and then released?

Also, I just checked my Windows root folder and see it is taking up 11Gb of space. I seem to recall some time back when I first got my system that it was not much above 8Gb. Why would the operating system file tree end up swelling by nearly 50% and is there anything within it that could be pruned without... Read more

Did you copy/paste the file itself or just its contents?

If you did copy/paste the file itself it's the same as a "file copy". If there is an error it's reported on the screen! There are many checking mechanisms on disk like CRC check for example (google yourself). And drive firmware itself can check if write was succesfull.

You have to trust win7 or the program that copies.... you can't check if 1000's of files are copied succesfull manually.

I downloaded a file, didn't download correctly, size = 0 bytes.

Reports owner unknown. I can't change ownership, remove file properties, any of that stuff. Can't rename or delete. I'm logged in as administrator but it keeps asking for administrator permission.


Another question about file ownerships - I tried to do a backup once, during an OS re-install, many files came back garbled, with file names switched around, many picture files had a file size but would not open, even if I changed the extensions, etc.

It seems easier to just copy files to an external, then copy back, than doing the windows backup. Is this what other's have found?

Is there any way to patch the file system to make it be able to support having files larger than 4GBs? Because I have a usb hard drive in which I have formated in FAT32 so I can plug it into my Playstation 3 so I can listen to music and watch movies. And there is some files I would like to put on it that are over 4GBs. I have heard of patching FAT32 to allow files over 4GBs on the file system but I haven't seen anywhere to get this patch. So I thought I would post here to see if anyone had any idea to get around this issue without reformating or changing the format of the drive.

I had completed a beautiful 82-slide PowerPoint presentation, but the wav file I embedded was HUGE (about 200 MB) and not to my choosing. I just had to have the music a certain length to span across 82 slides. Is there ANY WAY to reduce the size of this music wav file (so that it conforms to the 50 MB max file size for PowerPoint). I would rather embed this music file than to have a link. Any suggetions?

A:Reducing wav file size (audio file) for powerpoint?

I'm not familiar with PP but could you not convert the wav to mp3/ogg or other? Or split the 200mb wav into 4 * 50mb files?

As I say, I'm not up on PowerPoint, but workarounds..... ;-)

Does anyone have a file manager that will show files bigger than 4 GB?
Both windows file manager and Powerdesk 4-5-6 will only show up to the
4 gb size. There has to be something out there?? I have xp pro SP2 installed.

A:Incorrect File Size In File Managers

What it might be is that Windows XP with Service Pack 1 has a file limit of 4 GB.

You have to install Service Pack 2 to work with files bigger than 4 GB.

I'm having a problem with a system image (C: drive and System Reserved drive, that I made with a scheduled Windows Backup) and its size. I have a D: drive where I store it.

First of all, I noticed this in D: drive properties:

Used space of the whole drive is actually larger than the size of all the individually selected D: drive files, including hidden files.

Then I noticed this:

System image size reported by Windows Backup info is clearly larger than the size reported in the backup folder properties.

There's like 35 GB stored somewhere in the disk and I can't find them, how come this is possible? Is there something that I'm missing?

Thanks and sorry for my english.

A:"Windows Backup size" not reflecting actual backup file size

Windows backups makes a system image and a backup of the user folder of the user account by default.

So, that extra data is likely from your user folder.

Also be default windows backup will save multiple copies of your user folder on each backup, not just file changes.

Which also I think would explain this.

I went to SSDs on all of my computers some time back, but I still use WD RE4s and 2.5 inch WD Black HDDs for a variety of backup tasks and for storage in which the data will not be accessed for a period longer than is ideal to use a non-powered SSD for. On my Macs I am using El Capitan with OS X Journeled, GUID map, and FileVault 2 encryption. On my SP3 and desktop I am using NTFS with Win 10 64-bit Pro with BitLocker enabled on both machines. The OS and third party programs are currently up to date.

I've generally used ExFAT and the GPT partition map because it allows me to use it on all of my computers, and I have always used the default cluster size. However, I do not think the default size was the best decision for me because the size on disk is over TWICE the actual size.

If I am correct, the default Win 10 cluster size is 4k, and that going BELOW that is useful for the drives I have many smaller files on. Is this correct? Additionally, the smaller cluster size I go, the slower the drive will write, correct? Also, if so, how low do you advise going? I am still torn between reformatting outright or trying one of the programs that allows changes to a currently in-use drive. Any advice? Thanks!

A:Hard drive cluster size issues? Size on HDD over twice the actual size

For the a sector size of 4k to double your disk utilization you'd have to have a really tiny average file size. From your numbers shown the average size if I calculate it correct is 132kb (unless you have 1 massive file and 17,711 tiny ones) so a 4k size will make no difference.

You could check with TreeSize Free - it will tell you if you right click on the status bar and select it to be displayed.

EDIT - having checked the default for ExFat is 128k for drives over 32GB (https://support.microsoft.com/en-us/kb/140365) and when I tried to format an external USB drive that is what it picked. According to macbook - Reformat exFat with specific Device Block Size and Cluster Size - Ask Different OSX picks 128k also.

So if you had 128k as your cluster size minimum disk utilization would be 17,772 files * 128k = 2.17GB. So if all your files were just over this (say 132k which looks like your current average size) you would be using 4.44GB add a couple of big files and it could easily be 6GB.

I would check your average file sizes and also your current cluster size (you can use chkdsk as described in the AskDifferent link above).

The default is 4k for NTFS and I have always formatted ExFat as 4k also. Depending on your current setting reformatting 4k looks like a good idea.

As for how - copying the data elsewhere, formatting and then copying it back has to be the easiest, safest and most likely fastest way. You'll also get the disk defragmented automatical... Read more

I'm not sure if this should be posted in the Windows software forum or if the Hardware forum is appropriate so I'm starting here.

I recently purchased an external USB drive (WD My Book 160GB) as an external backup drive for my desktop. My question/issue is that Windows is reporting the available drive space at a value that is far less then the total size of the drive minus the sum of the drive space of the existing files on the drive.

For example, the My Book drive is 160GB. Using Windows Explorer I determined the amount of space the existing files & folders on the drive are using by right-clicking each file or folder in the root of teh drive and selecting 'Properties' and using the 'Size' and 'Size On Desk' values in the 'Properties' dialog. The sum of the 'Size On Disk' value of each folder in the root of the drive combined with the same for each file in the root equals 120GB (rounded to the nearest GB). According to the 'Properties' dialog for the drive (right-click the drive in Windows Explorer and select 'Properties') there is 15GB of available drive space.

120GB + 15GB = 135GB

What happened to 25GB of space on the drive?

I used Windows Disk Management to verify the drive space. According to Disk Managment the USB drive has a capacity of 149GB. This raises another question, what happened to 10GB of drive space? The thing is supposse to be 160GB and yet the capacity accoridng to Win... Read more

A:Available Drive Space < Drive Size - Sum of Existing Files

The short answer to there's two different measurement formats used. Decimal (GB) and binary (GiB) formats. Binary is used by Windows and decimal is used by the manufacturers. Both the manufacturer and Windows are giving you the "correct" number at about 149.
That explains some of it but honestly unless the external drive has a hidden partition, which is possible as some of them put on software to backup and also do a backup image file as well.

I had 8 video clips (AVI) each appx. 177-179 megabites. after converting them to mp4 and burning to dvd i was only able to put 7 of the clips on dvd. It said 7 clips took up 4.19gb of 4.70 not enough room for the 8th clip. Total size of all 8 clips is 1403 megabites. Does converting to mp4 make the files that much larger ?
