HP50G SD card STO and RCL

I am trying to make an exact copy of 2 directories on the calculator to the SD card. Each directory contains 2 programs. These would function as a backup on the SD card.
What confuses me is what the other user "Han" said about the files on the sd card being only compatible with a pc and not the hp. I used the same syntax that the User manual used to save a Dir/file to the card but when I view the directory from the file manager it won't show the program in the directory Ex. :3:"BASE/D-H" (enter on stack level 1) then STO.
