How about a fix using FB itself ? Try this to see if its just a dud resource-fork: PathToYourFile$ = "Macintosh HD:MY Big Program:RuleTheWorld.MAIN" OPEN "OR",#1,PathToYourFile$ CLOSE #1 END !!! Warning: Untested, Make sure you use it on a backup copy of your file !!!! !!! Don't try to fix the project file (.pi ) !!!
