This file is known to cause the following problems:
Computer running slow
Computer locking up
Server locking up
Files not opening
Files taking forever to open
Unfortunately this is by design. It's a temporary file intended for use with Adobe Bridge. Because of tighter integration in CS3 it is also used by all the other Adobe apps in the suite. Occasionally the file gets corrupted and you will start to experience one or more of the symptoms above. If that happens, close your Adobe apps, find and delete the file, and restart the computer. The restart is not absolutely necessary but is recommended.
