Hi Brenda ---

>all temporary dbfs are created using sys(2015). want to delete them all at application end. first i close all. then i tried "delete file _*.*", but that did not delete the files. then tried delete file with the full path name and _*.*, again that did not work. read the help on delete file and in one place it says you can use wildcards, but in the remarks it says you can not. any know how i can delete all the _ file?

=ADIR(aTemps,"_*.DBF")
FOR i = 1 TO ALEN(aTemps,1)
   cFile=aTemps(i,1)
   DELETE FILE &cFile
ENDFOR

This might help.
