Example case:
- Have Bunny.mkv.
- Have a Bittorrent v1 torrent with Bunny.mkv and other file(s) in it, and torrent pieces don't align to file sizes. Specify location of Bunny.mkv.

- if the file is larger:  file too large

I think a third green colored status might be a good addition if the file was coming from a merge:
98% - merged, file may be complete, but torrent piece is missing to verify that
