How can I fish out large files that are hidden?

By stereo19 ·
I have a user that I just issued a Lenovo Laptop with a 40Gb hard drive. It's been a week, and now he comes back and tells me that he only has 9GB left. What is going on here? i checked his PST's and his program files. I also checked his applications in add/remove to see if there were any rogue applications installed. It was clean. Anyone have any ideas?

Hidden files

by p.j.hutchison In reply to How can I fish out large ...

There are some common sources of hidden files:
a) Pagefile.sys = 1.5 X RAM.
b) Hiberfil.sys = 1 x RAM
c) System Volume Information = upto 10% HD
d) Recycle Bin = upto 10% of HD
e) Temp files = User and system temp files
f) OLK folders = Hidden temp folders used by Outlook when saving attachments which are sometimes not accessible via Explorer.

Still doesn't account for a 40GB HD to show 9GB

Right? I looked around and tried to probe some of those areas you had mentioned, but the math does not add up.

Windows hides the files

Even from itself. See my post below for a possible solution.

Have you loaded Disk Management console and checked out the disk partitioning?
Does the C: drive take up the whole drive or only part of the hard disk?

Live Linux

by NickNielsen In reply to How can I fish out large ...

Download and burn any Live CD Linux (I prefer PCLinuxOS, but that's just me). Boot to the CD and start the file manager. If the user has downloaded a series of large files (videos, etc.), these files are probably still on the drive in the temporary internet files.

You can also install and run CrapCleaner ( It will remove much of the detritus that Windows leaves behind.

Finding large files

by rey_daniel In reply to How can I fish out large ...

I would suggest using the DIR command but piping the output into a text file.

DIR C /s /ah /os >hiddenfiles.txt

creates a file called hiddenfiles.txt that contains any and all hidden files with location, size and date information.

Hope this helps....
