No, the Feel folder contains this:
There are two .log files, sounds and accu_feel, then sounds.pk and A2AfeelInstaller.exe_debug.log.txt.
Plus manual and unwise.
The two .dll files created by the Accu Feel.exe are in the Modules folder
Other information in case you need it.
Win7 Professional, 9 Gigs RAM, Acceleration.
I have all recent A2a accusim planes, J3 cub, P-40, P-47, Spitfire, B-17. They work like a charm. Actually, only 4096 texture size textures (like the ones by Tom Weiss) do not shimmer. This is not related to Accu Feel though, just came to my mind.
And just to be sure, I always click "save and exit" on the Accu Feel menu.
Should there be .dat files in the Feel folder?
