Pros
Works great for my music collection!

Summary
Multiple files and folders, nice interface.

Pros
The selling point of this application is the ability to do multiple files and folders and export a list of MD5 hashes.
Cons
It seemed slow, but doing a MD5 on a folder is kinda slow. Doesn't remember the folder you last did, so digging through the filesystem every time gets old.
Summary
It's good, i recommend it.
Easy to Use, Portable, Stand-alone

Pros
It's quick to use, direct to the point, and can be used anywhere.
Cons
Not that I don't like. I wish there's "Send to" function that would make md5 on selected files on-demand. After that, when Close(X) and/or the cancel button is clicked, it should close the program, not go back to the directory tree. How about CRC32?
Summary
Excellent program! No bad characteristics.

Pros
Fairly easy to use and works well.
Cons
So Far... I have not seen any real cons, but I like to use a program for a while before I make a final judgment.
Summary
Totally what I'm looking for!!!
