hi. what is the proper method to remove unused a/c from 2k2pro? tt

The way I do it is to take the entire folder and save it in another seperate directory on the HD. Or if you want just delete the entire folder for the specific aircraft. Be careful if things like sound or panels are aliased to other aircraft. If this is the case I will usually just copy and paste the panel or sound folder contents into the one that is using the deleted aircraft. It takes up a bit more space, but you then have individual folders and can move them as you choose. The only other big problem (if you have a storage space issue) is the gauge folder. Some like to delete gauges, I don't so mine is pretty big, but for me it causes less problem to just leave them there. So far my FS install is hovering around 7.5 GB. I clean house with the aircraft and scenery regularly.Hornit
