Relatively easy to use

Pros
The program works fine and is easy to use.
Cons
Installation and instructions are somewhat difficult to understand (i.e. how/where to install on both computer and USB drive).
Summary
I downloaded this program to protect USB flash drives I use for school. The USB drive I tested it on was access protected, rendering it inaccessible without the password, however the installation instructions were somewhat difficult to follow. I would strongly recommend "testing" it out on a USB flash drive you have no information on (just in case you end up having to format the drive).
Useful But easy to lose all files
zeldus
Pros
Safely Locks files through password protection, exactly what i was looking for.
Cons
must delete all files on USB before it will password protect.
If you delete the Password app you cant unlock the USB unless:
you copied the unlock App, click the release tool button on the program or, create a new password, which you to lose all data
Summary
Overall i am satisfied that this program does what its intended to do.
