Searching on the path can actually make your life much easier. Stuffing everything in the filename doesn't always work well.

For example, MAME rom files must have specific names, so if you share....

Emulation/MAME/Roms/...

people looking for "MAME roms" will find them. Without this you'd have to rename every rom to begin with something like "MAME ROM - pacman.zip", but this name won't work with the emulator making it so you can't share the same files you actually use.
