    I installed Windows 7 Ult 64 bit trough Windows XP, but I installed on my non primary HDD to back up files. Once the files were copied to the new HDD I re-formatted my HDD. I have an issue with My Computer recording the space usage.
    It says I have used 553.GB of my 111GB Drive

    But when I select all my folders (hidden and not) the total is 35.6GB I also got this number totaling each folder separate.

    So my question is where is the 19.6GB my computer is not accounting for?

    If I can't find a solution I might reinstall formatting both HDD's.

    Thanks for your help.

    Notice the top of your second image says Program Files (x86)

    The line in your second image that says all in c:\ is deceptive.

    You are just looking at the total of that specific folder.... program files (x86)

    Start at the top ... click Compter and look on the left for c:

    right click on C: and select properties.... Voilla ! Same Same

    Notice the comma and the ... after the Program Files (x86) and how all the folders are selected. This is what it would look like if I only had Program Files (x86) selected.

    Here are properties from all my folders in C:/
    13.2+16.7+.133+.938+.306+4.28=34.4GB

    34.4GB is no where near 55.2GB

    I never get a title saying \program files (x86) when I'm checking the properties of my drive.. note the big red circle
    On my computer the free space is reported the same in both locations

    Ok.. ok... ok.... I think I finally see what you have found.

    The lesser report is not including something that is there. There is a small difference when I did what you did... but not nearly like yours.

    Hi, I also have this problem. However it's on a bigger scale. All the folders on my C: drive add up to 48.5GB but on my computer it says I have "192gb free of 288gb"
    Any Ideas?
    Cheers

    Suppose we do find the reason... what are we going to do? Delete some hidden files? It doesn't look like any of us are about to run out of disk space soon.

    I'm curious and would like to know... but I doubt I will take any action in the end.

    Could it be a gigabyte vs gigabit difference, here?

    Gigabit = 1000mb
    Gigabyte = 1024mb

    They're both accurate, but they're both two different ways of measuring space. I found this out on my Ubuntu machine, because I saw my disk analyzer was showing my drives with space using GiB while when I checked system properties of the drive it showed up as GB, so I didn't understand why I was getting different numbers.

    I found out GiB is Gigabit, while GB = Gigabyte. Turns out the numbers were different because they were both measuring the used space in a different format.

    It adds up:

    1000 - 1024
    2000 - 2048
    4000 - 4096

    Perhaps that's it?

    He had a differnce of almost 20 gb... that lot.

    One posibility (for some difference) is that when you look at c: from the computer it is INCLUDING the hidden partition that Win 7 builds for revcovery... but that's only 100 mb by default. Maybe he upgraded or did something to make it larter. When you just add the file sizes it would ignore that partition.

    Is that not shown by "tools>folder options>view>show hidden files and folders"? I was including all the hidden folders that I was able to see.

    I think I will just do a fresh install and see how that goes.

    I know.. I already flipped that on and off to measure the effect.

    Now that I know you did an upgrade... I wonder where your windows.old file is .. and if it's included... it would probably be at least 20 gb.

    A clean install is wise.

    Could this be the answer. I found it on WIKI.

    Since the early 2000s most of consumer hard drive capacities are grouped in certain size classes measured in gigabytes. The exact capacity of a given drive is usually some number above or below the class designation. Although most manufacturers of hard disk drives and flash-memory disk devices define 1 gigabyte as 1000000000bytes, the computer operating systems used by most users usually calculate size in gibibytes by dividing the total capacity in bytes by 1073741824, but report the result with the symbol GB. This practice can be a cause of confusion, as a hard disk with a manufacturer-rated capacity of 400 gigabytes may be reported by the operating system as only 372 GB.

    I'm afraid it would be boring. I haven't had time to restore my porn collection. :eek:

    Mine is close enough.... he has definitely got something mysterious goin on to have 20 gb difference. I suppose he went off to do a clean install. That will probably cure it.

    I think before vista you coud use an Alt + keypad number from command prompt to rename a folder that windows could see but couldn't open or include in the math when it added up the total file sizes. They finally fixed that.
