What is an EKX file?
Encrypted Pokémon save file used by 3DS Pokémon games, such as Omega Ruby and Alpha Sapphire; contains information about a Pokémon, including its nature, the location it is encountered, abilities, battle stats, and attacks.
EKX files are encrypted but can be opened and edited in Windows using utilities like PKHeX (a Gen 6 equivalent of PokeGen). The EKX file is useful for injecting Pokémon back into the game for use.
