Rated 5 out of 5 stars

Uses minimal resources and makes it a cinch to add IAT support to your own extension.

Not sure why a previous reviewer is complaining about "undocumented" features, a very quick glance at the options plainly states IAT will clean up whatever folder you use as a cache.
If you use a folder with important documents in it then you should expect them to be cleaned as well...

Of course you'd expect important documents to be backed up

This review is for a previous version of the add-on (1.9.2).
