I try to save some stats per player in $profile in json files named after their steam Id to easily find them

problem is, after 500 files, the script unexpectedly says i have too many files in my directory.

This is for sure an engine limitation, as the Operating System (windows) allows 4.6 billion files per directory in ntfs

I tried to create a hashing algorithm with makedirectory, but
a) 500 is really a bad number for hashing maximum
b) it does not work, as it does not create any directory in $profile
