Can you still access Adobe PDF SAVED FILES WHEN YOU GET A NEW COMPUTER ? Do you loose the files you have saved on you old computer when you get another computer?
I may not be clear on what you are asking here but I'll try an answer anyway since that's the type of guy I am.
If you have PDF files on your old computer, you will need to transfer them to your new computer. You can use a flash drive or CD if needed.
But again, I think I'm not getting what you are really wanting to know. If I'm not, can you give us some more details?
