I am having the same problem as everyone else.

When I try to open a File or load a ZTool (both from the same project) I receive the “Out of Disk Space” message. I also have the same mysterious .zzz file in my project folder.

Concerning the problematic file: the Polycount was quite low, at 2,358 total points. The ZTool in the File has 30 SubTools.

I tried Aurick’s suggestion which may be responsible for my limited success in recovering the ZTool. His instructions were: Preferences > Undo History > turn on Skip Loading and turn off Enable Saving.

Aurick’s suggestion allowed me to load the ZTool and re-save both the ZTool and the File with a new name. However, even the new File and the new ZTool will cause ZBrush to crash within minutes. I said that I had limited success because while I’m able to recover the ZTool and the file, ZBrush crashes when I try to export an OBJ or use GoZ. So while I am able to view my work, I’m unable to do anything useful with it because it doesn’t stay open long enough for me to get the data out of ZBrush.

My System Specs: MacBook Pro, Early 2011 Processor: 2.3 GHz Intel Core i7 Memory: 8 GB 1333 MHz DDR3 Graphics: AMD Radeon HD 6750M 1024 MB OS: Mac OS X Lion 10.7.5

I have almost 600 GB of free disk space.

I will still submit a Support Ticket now.
