Some of you may have seen contrails that touch the ground and move along as they trail the aircraft way above. Last summer a chap posted on fsworld some Tweaks & Tips and one of them was how to do away with what I have come to call "Rooster Tail" contrails.
His fix: "When you added a new plane, especially if it had its own self-extracting .exe program, it probably had written over one or both of the default fx_contrail files in the effects folder.
Go to the Effects folder and look to see if the dates for the fx_contrail_l.fx and fx_contrail_s.fx files are at least 2003. When I did this, I noticed that one of them (can't remember) was 2001. So, I went back to the installation disk (disk 1), and copied and pasted the fx_contrail files back to the Effects folder in FS9."
You CANNOT find those two files on disk 1 or 2, 3 or 4. Essentially everything on those discs is in .exe format and unless you make another FS9 install, you cannot access individual files.
Short of doing that, WHERE or HOW can I get the bloody fx_contrail_l.fx and fx_contrail_s.fx ???
