in settings manue maybe a way to do bulk checksumming

[sign-out]

this would be after/if you choose to save the checksum to the file or not being able to like in the settings have it set a back ground task to check sum all your files

(would also be cool for it to if one is already there notify if the new one it does is different indicating file derogation )

(could also also if there are event hooks add a hook to check sum new files being added once they are fully uploaded )
