locking folders and files??

hi, i hope this is in the right forum......i have a powerbook g4 and i am the only user but occasionaly other people will walk up and use it. i have a lot of microsoft word files and i was wondering aside from being able to set a password to open them though word, is there any way to get the mac to ask you for a password either when you try to open the folder, or when you try to open the file. i have looked in the permissions section and it only works for other users....


thanks for the help

Sound like you will want to encrypt the file or folder. You can search either versiontracker or macupdate for an encrypt program.
