Guest OS disk usage almost twice as high as limit on dynamic disk

[bristi]

Hi

I have installed windows 8 as a guest OS from Parallels 8 running under OSX mountain lion. When I installed it I created a (dynamic) disk size of 64GB for the guest. Problem is that the guest is currently consuming 114GB disk space!

From inside guest OS it correctly resides on a 64GB disk and uses around 50GB disk space. I have 7 snapshots but they seem to use under 1GB in total. One of them has a crescent moon so might have been created while guest was hibernating. Compression is configured for the disk and there is no reclaimable space. Anyone know why this is happening - and how I can get my disk space back without deleting my VM?

I have sent a support request as well but it puzzles me that I can't find anything related in the forum or by googling.

This is the consumed disk usage of the guest OS:

Oh. My. God.

I wrongly assumed the snapshots were just small incremental files (I haven't really installed huge programs after initial installation) and that Parallels Desktop told the truth when it said that snapshots were taking up some 800MB (compressed?) disk space. just deleted all but the latest snapshot and now most of my disk space is back. Now the guest is using 74GB disk space - meaning that the single remaining snapshot is about 24GB in size. Come on Parallels.. I know it is messy deleting intervening snapshots but I didn't even install 24GB worth of programs.

Anyways. Sorry to bother you all - I just never imagined snapshots could be taking up that much space.
