performance are most simmers using. Compact, full or other?ThanksMikeOBTW ..this is the second time I post this question..the other..I do not see the first post !!??

I install full. That way it will not have to seek the CDROM for scenery information while you fly causing pauses or stutters.Sean

I got 40 gigs just for FS so I use full.JimCYWG

This is good timing, because I want to do a complete re-install of FS9 and all of it

Unfortunately, there is no "standard" way in which the various add-ons handle the Registry. Some make entries and some don't. So just deleting the FS9 folder may leave some strange stuff in the Registry which is hard to identify for later manual deletion. In order to keep the Registry as uncluttered as possible I always uninstall the add-ons first, then uninstall FS9, and lastly manually delete the main FS9 folder. Doing it this way I've never had the need to plow through the Registry looking for "stray" flight-sim related entries. Also, to help the performance of the reinstall a bit, I'd recommend defragging the drive after everything is uninstalled, defragging it again after the FS9 install, and then doing a final defrag after all the add-ons are loaded back.Doug

Thanks Doug..sounds good!Mike
