In my pocket pc i have the option to backup or save files to the:
-Main Memory
-Flash Disk
-Storage Card

Now, the storage card i know what is it: its the CF card that i bought; main memory i know too what is it, now about Flash Disk...? What is that Wish is the difference between that and the Main Memory?

I must admit that in the very beggining i thought that the Main Memory was the Cf card memory...


PS: I must say thanks to Freitas because he always answer to my questions and i must be really boring because i am always making such basic questions. So, thanks!
