Not quite sure how sharing folders on Mega works. As far as I know I can only share it with people who I add manually.
Put all your stuff into a folder on Mega.
Just as you provide the link to a single file, you can make a link to an entire folder.
They person who clicks the link will then be given the list of everything in that folder.

The list includes the upload date so if they remember when they last checked it, they can select only the ones that have changed since then.
