I mentioned earlier in the year I am focusing on reducing the overall amount of traffic in my inbox, and at the same time the amount of time spent managing my inbox. Â In my work life IBM Connections Files has greatly reduced the number of attachments received in email, and the ones I do receive are simply dragged and dropped into Files using the Notes Sidebar plugin.
In my personal life no such luck, I still get quite a deal of attachments in email, and I have found a pretty good system for dealing with them using a combination of Gmail, attachments.me, and Dropbox.
Using rules in attachments.me I have automated some common scenarios where I receive attachments, and have them automatically saved to Dropbox.  For example in the rules below in the first I have identified a couple of frequent senders of documents, which are saved straight to Dropbox where I can simply open them (and rarely do I have to go back and open the original email).  The second rule is even simpler when my Mom sends me a picture it is automatically saved to the appropriate dropbox folder.
Attachments.me also supports integration with Box, Skydrive, and Google Drive.
