Mr Pheer

I have 2 text files on a windows machine.

Lets call the first one "A"
Lets call the second one "B"

A is just a list of usernames that dont work
B is a master list of usernames

I need to write a new file, lets call it "C"

C needs to be a list of usernames that do work

So, if a username in "A" matches a username in "B", remove it
Output the good list to "C"

Complicated way to explain a simple process.

Anybody know an app that does it?
