Secondhand Macbook: 20 gigs of music files but cannot locate

[GinaMarie]

Hello everyone

I just purchased my first Macbook secondhand today. When I go to storage it says I have about 20 gigs of audio files but when I try to locate them in my files I cannot find them.

*I have Lion (but no start-up disks so I can't wipe the system clean)
*I deleted the other admin account and did not save a copy
*There is a guest account which I haven't accessed yet
*It's a 2009 Macbook with a 120 hard drive

Any help on how I can locate the files and erase them would be appreciated!

Thank you

Great thank you! I just downloaded Disc Inventory X. Opening it now

Okay using the tool it looks like most of the files are torrents under a user name. But that user name is not in the list of registered users. There's also a private file taking up about 4 gigs of space called 'var".

When I try to delta from the tool it says I don't have access to the folder.

How can I delete these files?
