As I said, VFP cleans up the temporary files if it exits gracefully. If it doesn't those files are orphans and you have to delete them manually. It sounds like there is something wrong within the system that is causing an error condition.

FWIW, you can cycle through the temp files and use the low level file functions (LLFF) to open them. If you can open them then that means VFP does not have them open and they are candidates for deletion. Immediately close them and delete them.

for lxx = 1 to adir(lafiles,"MyTempDir\*.tmp")
   lnhandle = fopen("MyTempDir\"+lafiles(lxx),2)  && open exclusively
   if lnhandle > 0 then
      =fclose(lnhandle)
      delete file (MyTempDir\"+lafiles(lxx))
   endif
endfor

You may have to debug this alittle as I did not test it.
