IE Cache Trasher deletes a file called "download cache" which can get quite big if you do not watch it. This file stores incomplete and complete downloads (the latter only if you set IE to remember your last completed downloads). It can grow to enormous proportions; mine was 119 MB the first time I checked.
Version 1.4 X of IE Cache Trasher has been completely ported to AppleScript Studio. The logging feature from version 1.3 X has been retained. If you do not wish to use the logging function, please use the included version 1.2 X. Numerous bugs have also been squashed.
Mac OS X 10.0 or later, Internet Explorer 5.
