Dropbox can save bandwidth and time by only uploading files it's not seen before.
Dropbox is a really useful file sharing, syncing, backup tool that quietly syncs my Dropbox folder with my other computers and with the online Dropbox website.
I use it to send my parents movies of my daughter; I use it to share my documents with my other computer and I get peace of mind knowing that right now there is a valid, complete backup of all my important stuff.
Here's the awesome feature
If I put a file in my dropbox that is the same as a file in anybody's dropbox (that's anybody in the world) then the upload is instant. For example, I've just purchased a download of MS Office 2010. It's 665MB big. When I put it in my dropbox, The Little Dropbox Elf (LDE) says,
Oh, that one? I've already got one of them. No need to upload another one, I'll just make a note of that.
Just so that you know — I don't actually hear the LDE. That would be annoying, and Dropbox is anything but annoying.
If you'd like to try Dropbox, you can sign up for a 2GB free account. If you sign up with this referral code, you’ll get an extra 250MB. So will I. Thanks.
