I have always been a big user and advocate of Dropbox which allows you after installation to have 2GB free of storage on the Dropbox servers and if you refer another person then you get a bonus of 500MB for every person that installs Dropbox up to 16GB.
Change a file on your computer , in your Dropbox folder and it is changed and synced on the Dropbox servers.
You can install Dropbox on multiple computers and when you change a file on one it is changed on all your computers.
This ” syncing ” is done when the computers are connected to the internet.
The Dropbox folder can be stored anywhere on your computer but is normally placed in your My Documents folder.
Dropbox can be run on Windows , Apple , iPhones , iPads , Android
On portable devices you install the app then you have access to your files that you have in your Dropboxfolder.
I like Dropbox for it’s ease of use and it’s syncing capabilities.
