One of the best pieces of software ever developed is a free software tool called Dropbox. Basically, Dropbox synchronizes a folder on your computer to the internet and any other computers you install dropbox on, for free (up to 2GB).
Any files you put in your dropbox folder will be synchronized to and from all devices (computers, phones, whatever) that you install the Dropbox application on. This can be an excellent way to share files between work and home computers, or to easily back up files. Further, you can also log into the Dropbox website to view and work with your files, meaning that they’re available to you from any internet-connected computer.
