>I've seen cases of strange behaviour when the local temp file folder has thousands of dead/orphan files. This can easily happen when a computer is used for several years and the folder has never been cleaned out. A PACK operation makes extra heavy use of temp files; this could be a factor. Maybe file-name collision, poor disk performance, ...

For that, I wrote this bit, which I call from the shutdown procedure, part of the cleanup on exit. Note the date (set to American).

PROCEDURE PurgeTemp
* 4/9/2001 dragan
	lcDir=SYS(2023)
	IF NOT DIRE(lcDir)
		RETURN
	ENDIF
	lcOnErr=ON('error')
	ON ERROR *
	LOCAL ldDay, lcFSpec, i, j, fname
	ldDay=DATE()-3
	lcFSpec=FORCEPATH('*.*', lcDir)
	N=ADIR(aa, lcFSpec)
	FOR i=1 TO N
		IF aa[i,3]<ldDay
			ERASE (FORCEPATH(aa[i,1], lcDir))
		ENDIF
	ENDFOR
	ON ERROR &lcOnErr
