Before, I have shared to you some free online storage websites that you can use to store your files. Skydrive for instance, offers 25GB of free online storage, while Google also offers more than 7GB. Recently, I discovered something even more amazing: Dropbox.
Dropbox is very useful for people who store their files in different computers. If you are using a computer at home, a laptop in your office, and storing some of your files in your mobile phone, then Dropbox is one way of safely storing, sharing and synchronizing them. View the video below for a clear explanation of how Droop box works.
Dropbox allows you to store for free up to 2 GB. If you want more storage space, you need to upgrade. For hosted WordPress blogs, there is a Dropbox plugin that lets you back up your files automatically.
