I noticed my system drive (Mac OSX 10.6.8) was filling up, so I used "GrandPerspective," a utility which makes a graphic view of the size of your files. To my surprise, a large part of my system drive is occupied by files from obsolete projects. The files take these two forms:
1. Can I safely delete these files? (especially since I'm using CS5.5 now)
2. Is there a utility within my Adobe programs which will find and delete these files for me with some degree of automation and precision?
