File number limit in the games folder

Is there a limit to the number of files that can reside in the games folder?

I ask because I have been dropping in nes files over last few days, to see what’s fun and what isn’t but not bothering to take any out. At a certain point the games stopped loading and the Tracker just froze on a blank screen. When I took a bunch away the nes files started loading again…

I would think it would be the same as the rest of the tracker folders at 100, but will double check.
