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

Hi Bob, thanks for the quick response..more questions. I have 65 File Folders, some only have one photo, other's have 4-12. Must I add all 65 folders to come up with an accurate number of MB's. I can't find any place that gives me a total of My Photo's. Steve

Create the PDF...save it to your local machine...drag/drop it to the flash drive...what could be simpler? Am I missing something?

I buy the flash drive wallets which have slots for each one in it, I have bought them at walmart for around $4-5 each and they hold several. You can put a label in the slot with the flash drive or if you have a label maker you can put a label or code right on the flash drive. If you use a code system then just put the list of codes in the storage wallet with those coded ones. You can also store a document on each flash drive that lists it's contents so that you just insert the flash drive then go to that document file to view what you stored on it.
