Dropbox instantaneously backs up and syncs your files over the Internet and to any computer or mobile device. After you install the application, it will create a Dropbox folder on your hard drive. Any file you put inside that folder will automatically be synced and monitored for changes, and each time a change is saved, it backs up and syncs the file again. Even better, Dropbox does revision history, so if you accidentally saved a file and wanted to revert to an old version or deleted a file, Dropbox can recover any previous version.
Any file that is synced with Dropbox is available on any computer you sync it to or through the Dropbox web interface.
With Dropbox, you will always have your files when you need it.
You get a 2 GB account for free to begin with.
However, this link will give me an extra 250 MB and you and anyone who wants to sign up with it the 250 MB bonus space. It would be a shame to waste extra storage!
I love Dropbox!
