Password protection. Partitions? Folders?

[gachenb@eis.calstate.edu (Greg R. Achenbach)]

Hello all.

I posted this question a while ago but got no responses, probably due to 
problems at the system I logon to.  Things were only getting posted 
locally, so you all probably never saw this question.  Here goes again.

I'm the principal of a school, and we just got our first hard drive a 
couple of months ago.  It's great.  My problem is that several people use 
this computer, but there are some things I would like to keep private.  I 
know I could keep the stuff on floppies that are locked up, but I would 
rather have the stuff on the HD.  I also know that I can password protect 
the entire HD, but that would prevent others from using it.  Is there 
some way to password protect a partition on a HD?  How about a folder?  
Any other ideas?

Thanks in advance.
