>Program Files. If I want to set up a path programatically to my VC++ >files (inside Visual studio) how do I know to use MICROS~1 rather than >MICROS~6? I dont know how to tell which short entry correlates to which long directory entry. But you can use always the long entry when you quote it. So use this: set PATH=c:\windows;"c:\program files\microsoft visual studio\vc98\bin" Bastian
