Need some help on comparing text files.

tlt1970s

I have 2 text files.

File A:
12345
ABCDE

File B:
12345
ABCDE
56789

Please suggest a easy way to compare the 2 files and remove whatever content that File A has from File B.

Meaning the result should be:

File B or File C:
56789

Thanks.

The ComparePlus plugin is your best bet for this sort of task.
I highly recommend this plugin for all Notepad++ users. I regard it as almost essential.
