The plugin brings the excellent CopyParty, which is a file server program. After toggling it on from the Decky plugin, you can go to the provided IP address on any of your devices, enter the password, and access the Deck’s files. You can manage files, upload or download files, and more. File transfer speeds are fast and resumable.
Here’s the GitHub for the plugin, although for right now it’s pretty bare on a description. For details one what all it can do, I’d recommend checking out the CopyParty link up above.
I just ssh to it with vs code. You get a console to install things with and what not, a text editor so you can write your own scripts or notes for things and a file manager to move things around. Idk if the speeds are the best though.
Ssh and ftp are great once they’re setup, but they’re not as simple as this, especially for non technical users.
This is also much faster than ssh/ftp for downloads and uploads. It breaks files up into multiple concurrent streams, in benchmarks it can hit download speeds of 8GB/s and upload speeds of 1GB/s (network allowing). It also does deduplication during the transfers, making real world transfer times faster than just the actual transfer speed.
I ssh into it with my file browser “Dolphin” on Linux (the same that is used in the Steam Deck as well). Needs to be setup first, but then I can access the files with the file browser. And secondary I ssh into it in terminal, but that is not to transfer files, but to have access to commands execution on the device (like installing something from commandline).
