I just tested it and it was very fine.
One bug report though: the file "serial" number (I don't remember how it's really called) was the same in the 2 test files - I don't know how you implement that particular number though.
I also have 2 question:
- Will your program work/compile under linux directly or will I have to go through wine or some such.
- Do you intend to release it soon?

Thanks for the good work.
