When I used F7 to unhide hidden files it is showing 0 byte Unknown File in my main C drive .

I am running Win7 64 SP1

Does the software not like win7 ?

Thanks , still cool and useful never the less.

YES! YES! Spent so many hours on this. I reinstalled XP and there was not a complete wipe for some reason. Here is how to see unknown stuff with more complete instructions:

Download this : http://assarbad.net/stuff/localsystem.zip

Then I found these instructions:

Right click on your WinDirStat shortcut > Properties, on that page > Start in: Copy the info on that line.
Start the executable (as Administrator) named “CMDasSys.exe” after unpacking the archive ( localsystem.zip ) to some temporary location.
Enter this in the dos window:

cd ( space after cd ) paste & hit > Enter.
Now type windirstat.exe to that line & hit > Enter.
WinDirStat will now fire up. Run WinDirStat and you’ll see everything. Delete the crap.
When finished with Command Prompt, close it.

I got rid of 90 Gb of images and music from the previous XP install.

Hi!
I have a windows server 2003 R2 with a C: partition with 60Gb capacity.
I’ve tried what people write in the comments, but I can’t find out whats exactly wrong.

you see, 85% (49,7gb or so) of my disk is allocated in the section. I’m not an expert and wasn’t able to figure it out.

if you have a Lenovo computer, the likely culprit is the Rescue and Recovery software. This is detailed in other entries across the web: you have to delete recent backups. I tried all the other things, but none worked, until I got onto the Lenovo angle.

Not really at all computer savvy but would just like to add something that worked for me with the same problem. I had a large ‘unknown’ file which I knew was there thanks to WDS but I couldn’t find it or delete it. I did suspect it was something to do either with page filing or with system restore but I had both turned off and had had them turned off for well over a year. (I have an Asus eee 901 pc with a very small solid state hard drive so they are luxuries I can’t afford). I tried lots of solutions, chkdsk, etc. but nothing worked. Finally, I tried turning system restore back on and then turning it off again and, hey presto, the unknown file disappeared. It may work for you.

bwquestion – Storage Manager – you mean Windows Snapshots. If so then yes that is one of the first things you should check. But from what I can tell, people usually come here only after they have fixed that and several other things like emptying temp folders…

Most of the problems people are seeing on server is from the local drive snapshots. By default it can use as much of the drive as is available to keep the snapshots.

You can go to the Storage Manager and right click the drive and select properties.
There will be a Snapshot tab. Adjust the size as needed and you will see the unknown file size adjust accordingly.

If it is a machine where you are positive that you will never need a previous version of a file, you can disable it in the same place.

@Justin-

Thanks for the clue on SpaceSniffer – for whatever reason WDS wasn’t showing me the space used by IIS logfiles, while SpaceSniffer did. Reclaimed 2GB there, which was sorely needed
