Apart from using them to just transport your data, there are a myriad other uses for one, as long as you have a one with a decent capacity and speed. For most of these uses, a 2GB drive (prices start at Rs 250) is more than sufficient, though as is always the case with digital storage, more the merrier!

It could be a folder of your photographs, videos, songs or important documents. Rather than take a complete backup of the drive which is a time-consuming process, you can use Microsoft's SyncToy to selectively backup and synchronise certain folders between the hard drive and an external USB flash drive. Once configured, all you have to do is plug the drive in to backup the folder.

A free application called Predator can be used for exactly the same thing. Download and install Predator, and pair a USB drive with it. With the USB drive plugged in, you can continue to work, but as soon as it is removed, the screen darkens, the computer locks, and keyboard/mouse input is disabled. Plug it back in, and normal usage is restored. Get it from: www .montpellier-informatique.com/predator Make a "life-backup" This can literally be a life saver. Many of us may have not stopped to think about what would happen if we lost all our belongings in a fire, flood or natural calamity. The size and portability of a USB flash drive is actually ideal to store digital copies of all your important documents like bank information, credit card details, birth certificates, legal papers, insurance papers and anything else that ties into yours or your family's life.
