In windows 7 they are here for me.
C:\Users\myname\Local Settings\Frontier_Developments\Products\FORC-FDEV-D-1002
Going to try and delete some latest ones again and see if I can get back in and grab a screeny for people to see who haven't got in yet while they wait for 2.02
Interestingly I have a FDEV-D-1001 from july and 1002, 1002 has recent timestamps in it, thought i'd mention other in case relevant to the bug
