Only got hex data???
Hexadecimal or binary - that is just a question of how the information is presented. The MMC (or the sample driver code) does not care about actual contents. Sample source code likes to dump the information in hex format, to make sure that any (!) information will be possible to present without any problems with character sets etc.
How to use a file system? Buy one from Keil, or surf for free sample code and figure out if it works - or write your own and then figure out if it works :)
But don't limit yourself to asking for all information. Search for it. Searching allows you access to much more data, and a lot faster. You can't spend your life asking for everything.
