https://briefcase.yahoo.com : Another great service from Yahoo!
I had been using this since early 1999 and even today my files stored then are stored securely :)
30 MB is enough to store few very important files online so that you can access it from any where in the world, at any time of the day.
Few good features are :
It has a simple and easy user interface, which allows one to organize data to be stored in hierarchical folders and further allows one to share any folder to selective or for all.
Multiple files can be uploaded and each file can have it’s own comment which makes it easy to identify files with similar names or odd names.
The integration of Briefcase with other Yahoo! servcies makes it even more attractive, one can save any email attachment in Yahoo! mail directly to his/her briefcase, this is a great feature.
