Hi,I am trying to remove the MSFS default AI aircraft with TTools.I Decomplie then remove all the entries from flightplan.txt, save the file then complie again. When I compile I get:ERROR: Unable to write to output file C:Program FilesMicrosoft GamesFS2002SCENEDBATCScenerytraffic_TEMP.bglAm I doing something wrong?thanks

The most likely problem is that the ' traffic_temp.bgl ' file is either set to read only or it has been opened by an application and therefore can't be written to.Locate the file in explorer and highlight it. Then right-click on it and left click on properties. Or you can select the DETAILS view including attributes.If the file is marked as read only there is your problem.If an application is opening the file and not closing it you will have to investigate further.

You've probably sorted this out already, but my guess is that you have to have something in the file - it can't be empty - to get an error free compile. Would be easy to check out though.:-wink2
