My son got me a flash drive for a Christmas gift and we used it to carry everything I wanted to have on my new computer by dragging the folders to the flash drive until it was filled, then transfered the files to the new computer. Then transferred the files on the flash drive to the new hard drive in the new computer.

each thumb flash drive will say what it holds for example it might hold 4 gig or 8 gig or less or more. It depends on what type files you will be storing, picture and video files are very large so will take up much more room than just text or document files. go to the folder of the files you want to backup to the thumb drive and right click on it and choose properties it will tell you exactly how much is contained in that folder so you would know you need a flash drive that is big enough to hold that much at least. I think 4 gig is a nice size and they are fairly inexpensive. I buy 4 gig Kingston drives at Big Lots all the time for $12. You can buy them at walmart, best buy, or any stores that sell electronics and computer stuff. I stick with the name brand ones like Kingston, San disk, corsair etc. Here is the link to some over at buy.com Results Within Our Stores general guide for using one Overview of How to use a USB Flash Drive

That'll help. You can always burn stuff to CD or DVD and transfer it or simply network share everything. I just bought an A-Data 4gb flash off newegg for the $20 area. If you already have a camara that uses SD or some other type of flash memory you can use that too with a $20 usb card reader. Networking everything is the simple free way though.
