Here's what John was refering to from ActiveVFP(a vfp mtdll):

lnNumber= ADIR(laGifs,SUBSTR(oProp.AppStartPath,1,ATC([AVFPdemo2],oProp.AppStartPath)+8)+'r\temp\*.gif')  && Create array
FOR i = 1 TO lnNumber  && Loop for number of files
IF DATETIME() - CTOT(DTOC(laGifs(i,3))+' '+laGifs(i,4)) > 1200 && files older than 20 Minutes, erase
	ERASE (SUBSTR(oProp.AppStartPath,1,ATC([AVFPdemo2],oProp.AppStartPath)+8)+'r\temp\'+laGifs(i,1))
ENDIF
ENDFOR

BTW, Timers will not work directly in a vfp mtdll. I'm not even sure they would work in a COM .exe called from a mtdll although I could be wrong(maybe 3rd party C++ timer would work).
