Arnstein Posted June 4, 2011 Share Posted June 4, 2011 I used the default settings for this program and executed a clean-up operation. Ccleaner proceeded to delete many temporary files. Unfortunately, "temporary files" is exactly where Parallels (http://http://www.parallels.com/) stores its data files. In other words, ccleaner destroyed my Parallels virtual machine. The specific folders that Parallels use are in /private/tmp. For example, my virtual machine is for Windows 7 with three disk partitions C: D: and E:. Parallels places the disk data in three directories /private/tmp/483/C /private/tmp/483/D /private/tmp/483/E The number 483 changes often. I don't know if there are other important files in /private/tmp. Believe me, the three folders that I have listed are important. I hope that you find this bug report to be useful.

bruceas Posted June 4, 2011 Share Posted June 4, 2011 The same thing happened to me! I ran CCleaner for Mac and it wiped out my Parallels virtual machines! If you're using Parallels on your Mac. run fast and run far from CCleaner! Link to comment Share on other sites More sharing options...
Alan_B Posted June 4, 2011 Share Posted June 4, 2011 If you're using Parallels on your Mac. run fast and run far from CCleaner! A better solution might be to Analyze first and exclude what you consider important - especially with a Beta release. Link to comment Share on other sites More sharing options...
eltel Posted June 5, 2011 Share Posted June 5, 2011 If you use the free ClamXav antivirus product it also deletes the clamd.socket file in /private/tmp and stops ClamXav Sentry working. I know this is free and beta but these are fundamental errors - doesn't seem to have been thought through - "let the user test it for us" springs to mind. Have flagged to ClamXav people as well.

Alan_B Posted June 5, 2011 Share Posted June 5, 2011 Perhaps the problem is that DOS invented TEMP as something to be cleaned at every startup because only worthless temporary junk got dumped there for a few minutes, and M.S. Windows as fostered the tradition that if you want to keep something then temporary folders are the last place to hold it. When a Windows application is crippled because it's Temp files are deleted I think what stupid application developers. Fortunately most Windows developers are not that stupid. Does Apple have a different purpose for "tmp" ? Link to comment Share on other sites More sharing options...
Winapp2.ini Posted June 5, 2011 Share Posted June 5, 2011 It sounds like it, Alan. It leads me to believe that the whole "anything you do will void your warranty" mac style of maintenance has lead developers to just not put anything where it should be, figuring no one will touch their temp folders. That is unless applications for mac just wont work when these files are placed in the program's directory, and I don't know if there is something akin to 'Application Data' on mac. winapp2.ini additions thread winapp2.ini github Link to comment Share on other sites More sharing options...
Guest MrRon Posted June 6, 2011 Share Posted June 6, 2011 We will look into this. Link to comment Share on other sites More sharing options...
Roger Crumley Posted December 2, 2019 Share Posted December 2, 2019 What about running CCleaner ONLY the Windows Version, and only "within" the Windows Virtual Machine? Link to comment Share on other sites More sharing options...
