unlocking (Win)password-protected file on CD


I got this question from a friend who has unwisely created a file on windows using password-protection and then forgotten the password after copying this on a CD. He has the CD. I wonder how Linux would interpret this password-protection. Would the
file be directly visible by Linux. I do not use Windows and have no
clue how password-protection works under win. Does this mean
that the file contents are encrypted?
I was asked if I have any advice on what to do. One obvious solution would be to run a crack program to try passwords till he gets it. But could there be a different simpler solution?

Thanks, svar

OK, I'll bite

It depends on what ver of Win, what type of file, was it zipped and encrypted? How was it encrypted and so on. Provide some details and I might be able to help.

Ok, I am told it was Win XP Professional, the file name is something like 1342.zip* and the password was only alphanumeric. That's all I know for now

Thanks, svar

Your best bet is to google for a zip password cracking utility. But be warned, depending on the length of the password, it could take some time to crack.

should not be a problem <=9 characters long, all alphanumeric
So the file contents itself are encrypted, so I should be able to open the file under linux, but see it scrambled, no?

try it! if the file was password-rotected by some versions of windoze, lin ux might just ignore the password. If, however, it was password-protected by winzip, it might be more difficult, and require a password crack utility. a word of warning before getting one, a lot of the sites with these programs on are (predictably) rather dodgy and full of illegal/obscene materials, and tend to shower you in ads and popups, so be sure to have a popup blocker handy. (or use firebird like me!)
