Lost Disk Space

So i recently reformatted my 120g Patriot Wildfire but my computer shows that i am missing a lot of disk space. The properties for the drive say that i have 83.8g of used space, but if i go into the drive and check the space of all of the folders(including hidden) i'm only using 52.4g. I'm running windows 7 64bit.

  1. Best answer
    Have you included the size of the swapfile and hibernate file (if enabled)? Those won't be in folders, and they're system as well as hidden, so it requires changing an extra option to show them. You could also try installing and running WinDirStat.
  2. 1) Run Disk Clean up on the volume(s) in question.
    - Sometimes you'll get bad queued/archived system bug reports.
    - There may be other 'extra's that are reported to Disk Clean-up that you can never see or access while logged into Windows.

    2) Run CHKDSK [drive:] /F
    - There might be clusters marked as used in the allocation bitmaps that are actually free/available. Check Disk can unmark them after confirming that they're not actually in use.

    3) Check for various 'shadow' files
    - System Protection, etc. anyone?

    "How much disk space does System Restore require?

    To store restore points, you need at least 300 megabytes (MB) of free space on each hard disk that has System Protection turned on. System Restore might use up to 15 percent of the space on each disk. As the amount of space fills up with restore points, System Restore will delete older restore points to make room for new ones.

    System Restore will not run on disks smaller than 1 gigabyte (GB)."


    Try disabling System Protection, restarting, then re-enabling it. (Unless you make weekly snapshots of your drive, or have other better Shadowing software).

    In Windows 7 you can configure System Protection somewhat, in Vista I believe it is locked at 15% (max) per volume.

    4) Boot a Linux LIVE distro and check the drive, Windows has lots of folders you may not even know about, and you cannot see the lions share of them whilst logged into the OS.

    I'll cross-link (pun intended if you get it) this thread with a new question that is related as it should eventually lead to more insight into this oft asked question:
    - How small can you compress your OS drive?

    so i tried doing a disk cleanup and cleaning all the system files didnt work, tried the chkdsk 2 times, and i have no shadow files or restore points. I'm going to look into Linux live right now.
  4. Load CMD.EXE
    CD\
    DIR /A /S
    That will show 'all' (according to Windows) files, and their total sizes.
    The folder count may be incorrect due to . and .. being counted as folders.

    Eventually you'll see something like:
    109,625 File(s) 21,276,578,295 bytes
    63179 Dir(s) xxx,xxx,xxx,xxx bytes free
  5. I figured out what it was by disabling "hide system protected items". It was the AI_RecycleBin folder, pagefile.sys, and hibr.sys. I figured out it was safe to delete AI_RecycleBin so i did, i turned off hibernate and i figured out that you can shrink the pagefile.sys depending on what you do with your computer and how much RAM you have. Going to read up on pagefile.sys before i change anything. The only thing i don't understand is how these files got so big as a result of reformatting the drive.
