I'd ask Lostpassword.com for which app to use for this.
I'm looking for something that i can use to change the ms excel/word password feature built into Office in one fail swoop. for example, pick a directory and change the password on every file in that directory / maybe even give me a report or log afterwards. i've got a group that manually sets the password on every document and thus, they never change it.. the files are being encrypted but they still want the piece of mind that there is a password that has to be used to view the continence.
