HelpMePls

All save files I seem to be downloading off of the internet are also 445Kb even though on the site it says 435Kb for example

Hi, I have been trying to get past this Alola Photo Club glitch I got by editing my "main" file in PokeHex but for some reason my file is 445Kb. Could you tell me why the file is corrupted and/or possibly fix it? I would be really grateful. Thanks main
