For a while, I was thinking of an alternative to this - since the first launch of the app would really go south only if the tmpfiles is pointing to a nonexistent or out-of-diskspace location, we may best launch it first without one. Then the app may find that it doesn't have the entry in config.fpw (or the file doesn't exist altogether), and may prepare one which would be used in subsequent launches. To do this, we may safely use PrivateProfileString functions - .fpw file actually has a structure of an .ini file, except the section titles, which I assume Fox would ignore.

[disclaimer: only parts of this were tested, some of them in older versions of Fox. don't try this at home, go to neighbor's. rated pg-12.999]
