Use something like

is_dir=DIRECTORY('C:\TEMP')

Re: Tempfiles:
VFP uses the default temp file area used by windows, normally you should have a directory like c:\temp set up and a statement in your autoexec.bat (I believe this is where windows is getting it from) like

SET TEMP=C:\TEMP


Everyone should have a temp file on a Local hard drive to minimize network traffic

Remember that the config.fpw is a pre-load file and the tmpfiles setting will override the default and cannot be changed once your program is running. So your testing for a temp directory from your program will not do anything for you. It needs to be set up beforehand.
