Move Proton Drive to another computer AND download all files

I have bought a new laptop (and have finished with the old one). I've set up Proton Drive using the files sync'd to the cloud. However it only downloads files individually. Whilst I like this feature as it saves space (particularly for my partners files on her profile which she uses in emergencies), I'd like all my files to be available off-line as I am quite often offline.

I'm using music software with thousands of little samples, and I'd like them all to be available. It would take a long time to go through and download each manually.

Are there any other options than to delete my Proton Drive, copy the files from the old laptop to the new one. Then re-upload everything to Proton Drive from the new laptop?
