In a CONFIG.FPW you can specify where to create temp files.

TMPFILES=C:\Temp
EDITWORK=C:\Temp
SORTWORK=C:\Temp
PROGWORK=C:\Temp

See VFP help on Config files for what each of these means.

>Hi everybody,

>I need to understand, where Fox tries to create temp files during INDEX ON and ALTER TABLE commands on huge tables. I was thinking, it uses current place for temp files, but it seems, like it uses current location of databases instead.

>I'd like to check for available space before running ALTER TABLE / INDEX ON command, and I need to know, how many space I need and where.

>My second question is: can we re-direct temp files to the specific location for the specific application (this application is run under another main application). If yes, how?
