Hi all! I just discovered an awesome tool called Attachments.me that indexes ALL the attached files you’ve ever had in Gmail, and organizes them into a nifty thumbnail view with incredibly fast indexed search. It tells you who sent you the attachment, when it came, what email thread it’s in, and lets you either View, Download, Share or Archive it.
Cooler still, you can set up special rules within your Gmail inbox to process attachments. For example, you can create a rule that automatically saves all images from a certain sender into a special folder in Dropbox. I’m going pretty nuts setting up special case rules like that. :)
It’s fantastic, it’s free, and I highly recommend it if you ever have issues tracking down attachments across hundreds of emails.
