I was recently using kde neon and tried out the vaults feature(for those not familiar it allows one to create encrypted folders without having the partition encrypted), something I have long wished for, is there any equivalent for MATE?
Maybe this will help https://www.makeuseof.com/tag/encrypt-files-folders-ubuntu/
does the caja-seahorse extension do this or is it for something else, I want a gui way to do it preferably
