password-protect folders external harddisk

[koswo]

Hello,

I have an external harddisk which I often borrow to friends. Since I also would like to store some confidential documents on that harddisk, I'm looking for a tool to password-protect folders/partitions on the harddisk.
Most of my friends have PC's, so I it has to be a cross-platform solution.
Does anyone know such tool?

Thanks in advance!

A quick and free way to do it would be to create an encrypted disk image (.dmg) file using Disk Utility. I'm not sure if you could open those files with the password on PCs, but they would be safe

OK, that indeed seems a good solution!

Thanks

As far as I know, .dmg files cannot be read by PC's, though I may be wrong. I know that RAR files can be password protected, maybe there's an app for OS X that can archive files into a password protected RAR file, might be worth looking into.

Fork out the cash for PGP. It's the best encryption program out there.

Or get GPG. It's free.
