Note: This app doesn’t give Windows the ability to read/write/format in EXT4/BTFRS. Click here.
If your drive appears to be read-only or you get a disk error when installing games after using DDM, please refer to our new Linux File Systems for Windows page.
This app lets you easily move Steam games installed on your PC to a Deck compatible microSD card (EXT4, BTRFS) and other external Steam Deck drives. This includes ensuring the game is copied to the proper location and that the proper ACF file is brought over so that the Deck knows the game is installed. Typically, this would be “prepping” a microSD card while you wait for your Deck to get delivered; so you can literally “plug and play” once you get it.
Other Uses: Add more games to an existing microSD card, flash drive, external drive, etc. that might be used as a Steam game installation destination (which does require EXT4 or BTRFS).
What it does:
- Allows you to hop around all your drives that have Steam game folders registered with Steam.
- It will scan and pull up a list of all installed games.
- You can then choose the games you want to migrate to the Deck drive by putting them into a QUEUE.
- Examine each drive in turn and queue up all the games that will fit (the app will ensure you do not exceed capacity and end up with “half a game” copied. A small “acf” file is a Steam file that tells Steam that the game is there – without it, you would have to manually “install” the game and let Steam “discover” files.
- Once you have a full queue, you can copy the contents to the designated drive that will be intelligently be displayed to you.
