Question about Sav Files and Pokemon games.

This question has been probably been asked before, and if so then im sorry.I have been wondering if there is a way to send a .sav file from my flash card (acekard 2i AKAIO) to my retail Pokemon game. I want to use my roms .sav file but ive only found ways to back up the .sav file from a DS card to your pc. Is it possible to send a .sav file from your pc to your retail DS cartridge?

No .
