Hello Jos,

Thanks for your reply.
yes, I verified everything and tested and tested ...

lc = GETENV('Temp') && my Temp-Dir
MkDir (ADDBS(lc) + 'Test') && works
MkdIr (ADDBS(lc) + 'Test\Test\Test') && doesn't work

The problem lies in specifying more than one non-existant subfolders.

Another anomaly :
? GETENV('TEMP') and ? GETENV('TMP') show the path as 8.3 ("F:\DOKUME~1\Matthias\LOKALE~1\Temp") while
? GETENV('HOMEPATH') and other show the path as long-filename("\Dokumente und Einstellungen\Matthias")

XP Pro and VFP8 here.
Could you try MkDir (ADDBS(GETENV('TEMP')) + 'Test\Test') and see if it works ?

Regards
Matthias
