Everyone from heavy Dropbox users to those who are wondering just what the fuss is all about with this cloud syncing business should be able to find something useful to them in this list.

If you’re unfamiliar with Dropbox it’s a sync service that keeps one folder, the drop box, on your computer in sync with the Dropbox server and any other computers or mobile devices that you have Dropbox installed on. It’s a fantastic way to keep a selection of files handy no matter where you are.

This is a collection of 10 of the most useful Dropbox services, apps and hacks that take Dropbox beyond convenient and into the realm of necessity. Note that this list focuses specifically on addons and tweaks rather than applications that feature Dropbox integration. We’ll take a look at those another time.

Keep browser addons in sync with Dropbox

If you travel between two or more machines using web browsers heavily then you know it can get a bit annoying trying to keep your addons and extensions all in sync between browsers. The Mac Dropbox addon MacDropAny allows you to set any folder to synchronize with Dropbox. Just pause Dropbox on both machines, set your browsers Addons directory to sync to Dropbox, then set any other browser you use to point at that folder on your Dropbox. Once you restart Dropbox syncing you will now have a completely harmonious Addons folder that’s shared between all of your browsers. Windows users should check out DropboxFolderSync.

Automatically download email attachments to Dropbox

MailDrop is an application for Windows that runs in the background and searches your IMAP inbox for emails with attachments to download. You specify a folder or label for it to search specifically so that it doesn’t just grab every attachment that comes in.  When you want it to download an attachment just move the email into that folder or change it’s label. Your file will be waiting for you in your Dropbox shortly.

Use Dropbox to host all of your game saves and program data

Dropboxifier The Top 10 Best Dropbox Services, Addons and Hacks

I always end up losing my game saves in hard drive crashes and computer moves. I’ve abandoned plenty of games because I’ve lost my progress to computer disaster. Dropboxifier simplifies the process of adding folders on your hard drive to Dropbox syncing. This doesn’t move the files it just references them so that Dropbox will back them up for you automatically. Add all of your games saved folder directories and any other folders you’d like backed up and you’re worry free. Windows only. Updated I’ve received some clarification from David Gagnon, the author of Dropboxifier as to the way that it works. It does indeed move your data into your Dropbox. It then creates a reference link so that your application looks to Dropbox to retrieve the data. This is similar to the way that Valve’s Steam Cloud service works. Thanks David!
