I had a strong wish to install Autodesk Revit 2013 just a days ago. Besides it needs 38 GB of free space, it did not fit on my clogged 100 GB system drive.
Too bad. Ok, my drive is oldish 160 GB Seagate, but still, windows7 seems like a disc hog.

So i’ve decide to investigate the case. Using RidNac, i made a small tour to the HDD space.


Well, windows 7 seems to use around 30 GB. Seems reasonable, until further investigated.
\Users uses another 30 GB. Pretty high for 2 active users, don’t you think?

So, where’s the space gone?

  • Mailboxes, fetched by prehistoric Thunderbird versions, uses ~2 GB
  • Another 150 GB is used by backup files, created by LibreOffice application suite. By the way, di you know they are created in “c:\Users\%USERNAME%\AppData\Roaming\LibreOffice\3\user\backups” folder? i would expect backups to be created aside the initial file, not heavens knows where and why.
  • Seems Autodesk Revit 2012 saves some files in “c:\Users\%USERNAME%\AppData\Local\Autodesk\Revit\Autodesk Revit Architecture 2012\Journals” folder. Some model files, journals, dumps can use as little as 1,5 Gb of space
  • 60 MB in c:\Users\%USERNAME%\AppData\Local\Microsoft\Windows\WER\ReportQuenue”. If “WER” stands for “Windows Error Reporting”, there was a lot of them …

This, some stuck files in %TEMP%, and user’s folders shrinked to 20 GB.

There is still some doubt about 13 GB files in “c:\windows\winsxs” and subfolders.

Of course, i could use “Disk Cleanup’ wizard, but it will not dig into some quite interesting folders.

By the way, Revit 2013 used 1 GB in “%PROGRAMFILES%\Autoddesk\Revit 2013”. Contents missing again, as in 2012 product line and is not to be installed via repair/reinstall process. Anyone can name the left-handers at ADSK?
