Sorting all different kinds of roms

[PiNPOiNT]

I was dumb and have stored all my roms for multiple different emulators all in the same folder, and i think its time to seperate them and clean up my hard drive a bit.  Is there any solutions you guys can think of to easily seperate all the different roms for different systems easily?

If you unzip them, most of the roms have different file extensions.  For example, NES is .nes, Sega Master System is .sms.  After they are unzipped, search for *.nes ect.. and put the search results in a new directory.
