need your help...

Is it possible to access the Owner's documents in Windows XP through a secondary admin account? Yes, I did Google.

....Why?
[Also- By reffering to the owner as "Owner" and not "Me" you have achnologed that the comp isn't yours..HaXoR?]

Actually its my brothers. He has a lot of music in his My Music folder. So just wanted to see if I could grab some..

change ownership of the folder

I don't think this works with the My Documents file.

..Ask him then?

If he enabled 'make my files and folders private' then there is no way for you to access them unless he logs in. they are encrypted.

No, I don't think he has it enabled.

If they aren't encrypted, just change his password and login as him :p

if they aren't encrypted you can access them through \Documents and Settings\Users\His Username\My Documents\

if they are encrypted you cannot

Restart the computer, enter Safe Mode, and log in to his account. If he's like 90% of the users out there, you'll have access to anything that you want. I would change things without deleting his password, unless you actually want him to know what you've been up to.
