Why can FlashSFV only process 1 SFV file at a time?

[DayCuts]

I would suggest you try hksfv, you can select a top level directory and the program will scan all subdirectories for all sfv files and create a queue of all files to check, then work its way through them. It old and has a few features that were also left incomplete or not working correctly, but it does the job when i need to check a lot of stuff.

Search for it on google, it's also freeware.
