Where is the temp folder?
OS X generates a programmatic directory stored in /private/var and defines the $TMPDIR environment variable for locating the system temporary folder.

Using Terminal.app, type echo $TMPDIR or open $TMPDIR (to open Finder on that folder).

There you will find temp files stored by the Applications running.

Since OS X is based on UNIX, there are several types of temporary directories, in addition the the "system" one where it stores things.


$TMPDIR which is generated like /var/folders/xl/84p38nhj405frmrkdpqb3v9c0000gn/T/
/private/tmp
/private/var/tmp
