Password recovery programs are available on the net, ive never had luck with any of them myself and just look for a new file also as said there is no proof the rar has the right files, if someone wants to attempt to crack it go ahead but then you do not know if 10 characters is even the right length or if abc-z was used if he added numbers it takes longer symbols even longer here are examples of times:
10 characters: look from D as thats duel core pc 163days
Upper Case Alpha ABCDEFGHIJKLMNOPQRSTUVWXYZ
Lower Case Alpha abcdefghijklmnopqrstuvwxyz
10 141 Trillion 447 Years 45 Years 4½ Years 163 Days 16 Days 39¼ Hours
From D again 253 days and thats just 8 characters!
