I just used Carbon Copy Cloner (CCC Version 3.5.7, Mac OS X 10.7 Lion).
Everything copied to my external backup drive except for about 500 random files - most of which are in the same folders and don't matter that much to me. I have three questions.
Is there any risk if I delete files from the following directories/locations?
/Users/user1/Library/Application Support/Firefox/Profiles/*- Some Firefox profile info
/Users/user1/Library/Caches/Firefox/Profiles/*- Some Firefox profile info
/Users/user1/Music/iTunes/iTunes Media/Music- A few audio tracks
/opt/local/var/cache/fontconfig/*- Probably related to the Macports fontconfig port
/private/var/tmp/tmp.*- I'm unsure what will happen if I delete these
Also, Carbon Copy Cloner gives me a way to access the location of 1 file at a time to manually move it to the Trash for deletion. Is there a way to delete them more than 1 at a time?
Lastly, Carbon Copy Cloner recommends that after I delete these files and finish my backup that I reformat my internal (source) hard drive. Is this really necessary?
