CloseReview for Attachment Extractor by Trippet
Rated 4 out of 5 stars
This is Far better than dragging and dropping, or clicking and confirming, each individual email. It's bare bones, but it works.
There is a warning before deleting attachments from emails to help avoid that faux pas. Make sure to hit Cancel. I once did not pay close enough attention, and my emails were duplicated with some of the duplicates retaining the attachment (thank goodness), but not all.
It works well for me as-is. The only extra I ask for is the ability to set my own naming parameters as the default, rather than the program's options being there every time. I'm willing to pay that small price, though, for the overall convenience of the add-on.
