If any of my regular expressions can be simplified please fix them! –  bbodenmiller Jul 3 '12 at 6:47
    
added some details from ehow.com/about_6565278_type-files-can-deleted_.html –  bbodenmiller Jul 3 '12 at 6:47
    
    
also look for crashplan defaults in my.service.xml. –  bbodenmiller Oct 21 '12 at 23:06

Linux: Everything ending with a ~ (backups from several editors). And to "optimize" your regexps, just a short example:

(?i).*\.(tmp|temp|part|bak|\~)

Won't this result in searching for ".~" rather than "blahfile~"? –  bbodenmiller Jul 3 '12 at 0:50
    
Ooops -- sure, you're right, that part I messed up. Intention was to shouw how to combine the regexps. But you're absolutely right: the \~ part is wrong there and must go in a separate line. –  Izzy Jul 3 '12 at 6:39
