I have found an interesting website called DropBox in the USA. This is a special service which offers cloud computing. All cloud computing means is your data is on another computer.
The program adds a folder in your Windows Explorer or Linux Nautilus file display folder, and whatever you add into that folder is added to your DropBox cloud account and is immediately visible and shared on each of your computers and/or your smart-phone. However, you have to register (free) each computer/phone on their website but from each computer/phone. Mine, for example, is visible on my Linux machine, my Netbook and my HTC Desire smart-phone.
You can grab a link for any individual file and send it to someone who can view it without a DropBox account.
There is also provision to share folders but this is done a different way. Each person you share it with must have a DropBox account. And once they have clicked on the link to share, that folder is also visible in their DropBox folder. This is very handy for sharing files that need constant updating with your family, friends or office workers. My wife and I share a folder and, as she uses Windows, it is very useful for sharing files.
When you join DropBox you have the opportunity to select 2GB of storage space which is free or, if you want to store all your files on DropBox (they will do your back-ups) it is $9.95 (£6.42) a month for 25GB or double that for 50GB.
The nice point about the free 2GB choice is, you get a bonus of 256MB when you perform five of the six examples of learning how it works. This is a good deal as you get to know how it works by performing these requests.
You also get a bonus when you introduce anyone. 256MB for both you and the new person so everyone gains. I use DropBox so if anyone contacts email@example.com before signing on, I will send you a link to use so we both gain a 256MB bonus.
