I cannot access virtual hard disk

I have been using my Parallels and Windows XP and suddenly I cannot access it. It says my hard disk image file is used by other application. I have no idea what it is talking about. Any help will be gratefully appreciated.

 

Hello,

please in the Finder, browse the virtual machine folder (the default path is: Documents-Parallels-Virtual Machine).
Find and delete the ".sav" and ".mem" files in the virtual machine folder.

If you still have this problem please try to do the following:
1. Find your Parallels hard disk file whose name ends with .hdd. Usually it is located in the Macintosh HD/Users/YourUserName/Library/Parallels/ or Macintosh HD/Users/YourUserName/Documents/Parallels/ folder. You can use Finder to find the .hdd file.
2. Right-click the file and choose Open Package Contents from the pop-up menu.
3. In the window that opens, you should see the lock file - it ends in .lck. Just drag it out of the package window to your desktop (don't touch anything else).
4. Close the package window and you should be able to start up Parallels with no issues. Once you've verified Parallels starts up OK, you can trash the .lck file..

Best regards,
Stacey
