I'm wanting to transfer all my CD's to an external hard drive, then to an Archos 504 to take with me traveling while I leave the hard drive at home as a back up. Selling the CD's. I'll use the Archos to play music on an audiophile quality stereo so want to keep the highest sound quality. Will be doing this for 400-500 CD's so expect to be up late nights WMA, ATRAC, OGG, FLAC, LOSSLESS, ENCODING, CODECS, BITRATE. I only know these have something to do with what I want to do. How can I learn the basics of doing what I want so I can get it all done? As you might guess, I know little about the technical workings of my computer. I have a Dell computer. WindowsXP. Thanks for any help.
