GameHydra moves installed games onto your other drives, so your launcher still finds them and always has room for the next download.
Free: one launcher, one drive · Standard: $29 once · Windows 10 and 11
The problem
Free space on the install drive. When that runs out, the next download will not start, and the usual fix is uninstalling something you still want. Meanwhile the other drives in the machine sit half empty, because moving a game there means telling your launcher about it and doing it one game at a time.
GameHydra keeps that number high without you managing anything.
What your launcher opens
C:\Steam\steamapps\common\SomeGame\Unchanged. This is the path the launcher recorded at install time and the only one it uses.
Where the files are
D:\GameHydra\SomeGame\The whole game, on the drive that suits how recently you played it. Never split, never partially moved.
How it works
A game installed to your main library lives in a folder the launcher records, and it uses that path for launching, updating and verifying. Everything it does with the game goes through that one location. The paths below are Steam’s; Epic Games, GOG Galaxy, EA app and Ubisoft Connect record their own the same way, and every step after this is identical for all of them.
The whole game folder is copied to an included drive, and only then removed from the original location. A game is never split between drives and never left half-moved — if the copy is interrupted, the original stays exactly where it was.
An NTFS junction is created at the original path, pointing at the new one. A junction is a directory-level link that Windows resolves inside the file system itself, below the level any application sees.
The launcher opens the path it recorded. Windows follows the junction and returns files from the other drive. It does not know a junction is involved, because nothing in the file API tells it. Launching, updating, verifying and uninstalling all behave normally.
GameHydra manages Steam, Epic Games, GOG Galaxy, EA app and Ubisoft Connect together, on the same drives and by the same rules. Free manages one launcher, whichever you pick; Standard manages all of them.
What it does
Steam downloads move off the install drive as they finish; games from your other launchers move the next time GameHydra organizes.
Recently played games sit on your fastest included drive. Games you have not played for a while move to the slowest.
An NTFS junction stays where the game was, so the path your launcher recorded still resolves.
Games you have not played in a while are compressed in place, and decompressed when you launch them.
A game that is running, or that its launcher is still installing or updating, is never moved.
Bring everything home restores every game to its own drive and removes every junction.

Pricing
One launcher, one drive, whenever you say so.
Set it up once and stop thinking about drive space.

In development
We’re designing a USB dock that holds up to four of your own drives and grows with snap-on extenders, so GameHydra can see every bay and what’s in it. It has no price and no date yet, and you don’t need it: GameHydra works with the drives already in your PC.
Questions
No. A junction is resolved by Windows inside the file system, below the level any application can see. Your launcher opens the path it recorded and gets the files from the other drive. Launching, updating, verifying game files and uninstalling all work exactly as before, because as far as your launcher is concerned nothing changed.
Your games keep working. A junction is a plain Windows feature, so a game that was moved still launches from its new drive with GameHydra gone. Uninstalling does not bring games back on its own: if you want every game back on the drive it was installed on, press Bring everything home first, then uninstall.
The games on that drive become unavailable until you plug it back in, in the same way they would if you had installed them there directly. The junction remains and resolves again as soon as the drive returns. GameHydra will not move new games onto a drive it cannot see, and it flags any game whose drive is missing rather than letting the launcher fail silently.
Games are only ever moved whole, never split across drives, and a game that is running, or that its launcher is still installing or updating, is never moved. Saves are safe either way: a game that keeps its saves inside its own folder moves with them, and the junction means the game still finds them at the path it expects. Saves kept outside the game folder, including Steam Cloud, are not touched at all.
The free plan manages one launcher across one extra drive. If it earns its place, Standard is $29, once.
