By now a good number of you have probably heard of Dropbox, free online storage space.

Basically, the way it works is it gives you 2 gigs of storage space online, to put anything in. The upload and download rates are extremely fast, delivering files in seconds, and you can grab said files from anywhere with their file manager online.

The awesome thing about it isn't the storage space really, the awesome thing is their public folder, and shared folders, along with their desktop syncing.

The public folder lets you publically link to anything you put in there, as if it were hosted on imageshack, or another file upload site. You can even change the file in the folder and whatever it's linked to will update as well, so no need to reupload files.

You can share folders with other members of dropbox, allowing you to pass off files easily. I'm using it in joint projects so that we can update parts and not have to worry about passing around the most recent copy.

Their most touted feature is of course the desktop sync. The desktop sync merges all changes that you make to your dropbox to a folder you pick on your computer. You put a file in that folder, and bang it's online. You change something somewhere else, and bang, all the other computers hooked up to your account have it too. The dropbox sync program has Windows, Mac, and Linux variants, so you can even do it across different operating systems.

Recently dropbox added a referral service, that gives you up to 3 gigs of extra space for referring other people (250 MB for each person that signs up). The best part is that the people you refer get the space too. Here's my referral link, if you sign up under this link, then you can get extra space.

Of course everyone is asking what the catch is. Free file storage up to 2 gigabytes (5 if you refer people, or are referred). The catch is that if you want more space, you gotta subscribe (subscribers can get 6 gigs of extra space for referrals, as opposed to only 3). If you only move around small files like pictures and so on, then 2 gigs is more than good enough, and the subscribers who need the extra space keep the thing running for the rest of us.
