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?

  1. /Users/user1/Library/Application Support/Firefox/Profiles/* - Some Firefox profile info
  2. /Users/user1/Library/Caches/Firefox/Profiles/* - Some Firefox profile info
  3. /Users/user1/Music/iTunes/iTunes Media/Music - A few audio tracks
  4. /opt/local/var/cache/fontconfig/* - Probably related to the Macports fontconfig port
  5. /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?

    One question per question is best since it's hard to select from multiple people attempting to answer three clear questions - worse, if one or more isn't super clear, it's hard to edit a question into shape. Why not edit this down to the one most pressing question. And if you need to ask a second before the first is answered - link the questions together? – bmike Jun 7 at 22:09
