Windows 7: 169GB unknown file in windirstat

26 Sep 2016   #11

windows 8.1
I agree, TreeSize Free is better than winDirStat

After spending weeks trying to find the missing space of 146GB, it turned out to be the printer spooled file which I was able to locate through TreeSize Free
I deleted it and it is gone

I used to use treesize all the time, but I've since switched to WinDirStat. Very powerful tool with a killer graphical interface.

Run WinDirStat as Administrator. The "Unknown" space will likely show up under the \Windows directory, or somewhere you can identify it.

I found 70GB in \Windows\temp\cab_*, which I backed up to an external file and deleted all but the last month's. There is also lots of space wasted by C:\Windows\Logs\CBS\*.log

These files were not deleted by the Disk Cleanup process.

You can delete the files on C:\Windows\SoftwareDistribution\Download
They were used to update and now useless.

Windows 7 Professional

I had a similar situation on a Windows 7 laptop where nearly 500 GB was "missing" on my system partition. The partition was full, but Windows Explorer was unable to detect the missing space, and the "windirstat" program simply showed a 500 GB "unknown" entry.

However, the TreeSize Free (Administrator) program (TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs) was able to show what the problem was, namely that someone had misconfigured the Cobian Backup program such that the source and destination directories were the same. As a consequence, it recursed until the partition filled up AND made nearly infinitely long directory paths that neither Windows Explorer nor windirstat were able to handle.

Perhaps needless to say, none of the Windows directory removal tools, including cmd rmdir, would work to remove this mess and it was with great difficulty that I finally managed to clean it up.
