Many people who move back-and forth between several computers use FTP (File Transfer Protocol) to upload data to remote servers and can access the data from any computer connected to the Internet. However, if file transfer is all you need, web hosting can be too complicated and expensive. However, there is a solution one a software program that is currently free called, Cloudberry Explorer the other is a extremely inexpensive service called Amazon S3. First you need to get a S3 account. S3 allows you to upload and store data on Amazon’s servers and only pay for the space that you use and the per-gigabyte price is extraordinarily low, only 15 cents per gigabyte per month. This is great for just transfering files where ever you are and only pay for what you need. The real star however, is Cloudberry Explorer, which looks just like a regular FTP program like Filezilla but, lets you upload files to your Amazon S3 account! There is a freeware version as well as a Pro version that is free for now while it is in beta and adds encryption and lets you move files from a FTP server to S3!  The interface is very simple and intuitive and my one and only gripe is that it is Windows only right now and I think inorder to fully grasp the theory of Cloud Computing is to run on all major operating systems but, it is great to move your data with you without having to carry it!
