Game library manager for Windows — 2026

Your games, asleep
until you need them.

Eudo moves the games you aren't playing to an external drive or NAS, and brings them back in minutes. Nothing to uninstall, nothing to download again.

From archive to playable.

A sleeping game is a compressed archive on your external drive. One click brings it back to the SSD, ready to launch.

Built to stay out of the way.

App archiving, as on Android, for your PC game library.

  1. 01

    Automatic

    Games left unplayed for a set number of days go to sleep. Eudo asks first.

  2. 02

    Predictive

    Eudo learns when you play and starts waking a game before you open it.

  3. 03

    Safe by design

    Every file is checksum-verified before an original is deleted. Every operation is logged and can be undone.

  4. 04

    Multi-launcher Soon

    Steam first. Epic Games, GOG and Battle.net next, in one library.

How it works

Questions

What you'd want to know before trusting software with a 100 GB folder.

Will I have to download the game again when I restore it?

No. Eudo copies the files back to their original location and Steam sees the game as installed. If an update came out while it was asleep, Steam downloads only that update.

What happens to my save files?

Eudo doesn't touch them. Saves live in Steam Cloud or your Documents folder, not in the game's install folder.

What if my drive is unplugged mid-copy?

Nothing is lost. Originals are deleted only after every copied file passes its checksum. Interrupted operations are recorded and can be resumed or rolled back.

Does it work with Steam open?

Eudo waits until Steam is closed before moving anything, then restarts it when it's done.

Is this allowed? What about DRM?

Eudo moves your own files to your own storage. It doesn't redistribute anything, touch DRM or modify game files.

Which platforms are supported?

The first release supports Steam on Windows 10 and 11. Epic Games, GOG, Battle.net, NAS targets and Linux / Steam Deck are on the roadmap.
