Windows 7 tells me that there is ~25GB free in Local Disc (C:) but when I navigate inside, if I select everything and look at properties, the size is different. Take a look at the screenshot to see what I mean.

Screenshot of problem

Any ideas as to why is this happening? It doesn't make sense.

Not everything is included there:

  • The contents of the Recycle Bin (C:/$Recycle.Bin ) (4 GB on my system)
  • System Restore data (C:/System Volume Information) (20 GB on my system)
  • Various other system files.

Tools > Folder Options should have an option to toggle the display of those system files.

So the "My Computer" window with the size of the Hard Drive in red is the CORRECT size? – Hristo Aug 2 '10 at 17:24
@Hristo: Yes it is. – Macha Aug 2 '10 at 17:40
@Macha... Thanks :) – Hristo Aug 2 '10 at 18:06
all hidden files and system files are visible. inconsistency still present. not sure what is going on. recycle bin is empty. – Hristo Aug 5 '10 at 4:52
How big is the gap now? – Macha Aug 5 '10 at 13:27

Are you sure you can see hidden/system files? It seems like I should see a swap file in your root if that was enabled but I don't.

haha... not my computer... I'll have to check that when I look at the computer again. Thanks – Hristo Aug 2 '10 at 17:24
Dude! why did you vote almost all my post down?(even accepted solutions are -1) This is a community forum design to help each other. – djshortbus Aug 2 '10 at 21:21
@djshortbus: If you were bulk downvoted, the system should detect it, and remove it within 48 hours. – Macha Aug 3 '10 at 15:41
back to the question... yes all hidden/system files are showing. inconsistency still there. – Hristo Aug 5 '10 at 4:52

Could also include Data Streams, that aren't shown at all, but are there

It's very likely due to automatic backups and system restore snapshots.

Try disabling Shadow Copies and you should see it go up.
