How to perminatly decypt ("export"?) a folder bigger than the free space on your device

I’m confident that this has been asked before. Couldn’t find it; please forward me there if so. Thanks!

I have a folder with 95gb of important files. If the free space on my computer is somehow less than that, how can I permanently decrypt my folder, such that I no longer need Cryptomator, without dragging and dropping the folder into my desktop and thus copying everything to it? (Because then I’d need to have both the encrypted folder and a decrypted copy at the same time, exceeding my space limit.)

Depending on which cloud storage you are using, you can enable files on demand.
Or you can access your vault directly online (cyberduck)
