help with file copying

Hi i am wondering wat to do if i have copied files from my 4 to my documents can i delete the ones in the 4 and put the one that were copied back in to my 4 ? will tghey still work.?? :-\

4? I am going to assume you mean the R4 flashcart. You can copy your game files to where ever you like if your wanting to clear your card without loosing your current games and save files, basically by "backing up" whats on your card to a folder on your HD and format the card if you wish and reload different games. And if your wanting to go back and play the ones you "backed up" then just copy/move them back to your flashcart. again I am not sure what you are meaning, but I hope that all made sense IF that is what you was asking.
