When you use one tool extensively, even a small improvement can mean a great deal. For the more than 45 millions who use Dropbox, uploading files just got easier.

Users know that merely dragging a file into the Dropbox folder is all that is required to upload it. But what about when you are working on a computer which does not have the Dropbox software installed?

With this recent improvement, you can go to Dropbox on your web browser (Explorer, Firefox, or Chrome), and drag a file from your desktop into the window on your browser. Dropbox uploads the file. Similarly, if you want the file to go into a particular folder inside Dropbox, drag it to that file in your browser’s window. Dropbox does the rest!

To help users learn about this new feature, Dropbox has posted about it on their blog. Even better, if you click the normal “Upload” link, the first thing you see is a box explaining the new improvement.

As of October 2011, more than 45,000 people were using Dropbox. If you are not one of them, there is no better time than now to create a free account.

Normally, you would get 2GB of free storage. Using the link above gives you an additional 500 MB and also gives me an additional 500 MB. As you set up your account, you will see how you can get additional storage (up to a total of 16GB for free) by introducing others to Dropbox.

I have said many times, we do what it easy. This new improvement makes a user-friendly service even easier.
