I don't think that the number of files...has anything to do with the crashes.
I have a ton of media files (.avi, .mpeg/.mpg) stored on various partitions in multiple folders exceeding 1TB...I've never known Explorer to crash, regardless of what my view options may be, at the moment.
IMO, chances are that you either a corrupt file in said folder...which can cause the system to freeze/crash, IME...or you have a malware possibility. Especially so if said crashes don't occur on every folder with media files.
FWIW: WMP is the default player for all media files, unless something else is elected as the default. In order to elect a different player...you need to install one. Have you installed an alternate player...and tried to use it on your files?
