Running out of room on your boot SSD is a rite of passage in PC gaming. Modern titles routinely eat 80–150 GB each, and a single 500 GB drive fills up fast. The good news: Steam can relocate installed games to a different drive in a few minutes without a 100 GB re-download, as long as you use the built-in library tools instead of dragging folders around in File Explorer.
Set up a second Steam library folder
Steam supports multiple “library folders,” one per drive. Before you can move anything, you need a destination library on the target drive.
Create the library
Open Steam → Settings → Storage. Click the drive dropdown, choose Add Drive, and pick your second SSD or HDD. Steam creates a steamlibrary folder there automatically. This is the correct way to register a drive; copying game files by hand leaves Steam unaware of them and forces a “discovering existing files” scan that often fails.
Move games in bulk
Still in the Storage screen, select the source drive, tick the checkboxes next to the games you want to relocate, and click Move. Steam validates and transfers the files, updates its manifest, and deletes the originals when done. You can also right-click any game → Properties → Installed Files → Move install folder.
How long does it take?
Transfer speed depends on the slower of your two drives. Moving between two NVMe SSDs is fastest; moving to a mechanical hard drive is bottlenecked by the HDD’s sequential write ceiling.
| Transfer path | Typical sustained speed | Time for a 100 GB game |
|---|---|---|
| NVMe SSD → NVMe SSD | 1,500–3,000 MB/s | ~1–2 min |
| SATA SSD → SATA SSD | 400–500 MB/s | ~4–5 min |
| SSD → 7200 RPM HDD | 120–180 MB/s | ~10–14 min |
| Re-downloading (300 Mbps line) | ~37 MB/s | ~45 min |
Even the slowest local move beats re-downloading on all but the fastest gigabit connections, and it doesn’t count against any data cap.
Should you keep some games on the fast drive?
Yes. Put the 3–4 games you play weekly, plus anything with heavy texture streaming (open-world titles), on your quickest NVMe drive. Park backlog games, older titles, and anything with mostly loading-screen level transitions on the slower drive. The real-world frame-rate difference between SATA and NVMe in most games is small, but load times and traversal texture pop-in improve on faster storage.
Other launchers
Epic Games Store and EA App can also move installs, but their tools are clunkier — Epic historically required a reinstall or a manual folder move plus re-scan. When a launcher lacks a clean move feature, a free tool like a symbolic-link (“junction”) helper can redirect a folder, but Steam’s native mover is safer and should always be your first choice.
FAQ
Will moving a game break my saves or achievements?
No. Cloud saves live with your account, and most local saves sit in your Windows user folder or Documents, not inside the Steam game directory. Achievements are tracked server-side. Moving the install folder only relocates the game’s program and asset files.
Can I move games while Steam is downloading updates?
It’s best not to. Pause any active downloads or updates for the games you’re relocating first. Moving a game mid-update can corrupt the manifest and trigger a full “verify integrity” pass, which wastes the time you were trying to save.
External drives and verification
You can move games to an external USB SSD too, which is handy for a large library or a laptop with limited internal storage. Register it the same way — Add Drive in Settings → Storage — but be aware that USB enclosures and cables vary wildly in speed. A good USB 3.2 Gen 2 NVMe enclosure can sustain 800–1,000 MB/s, plenty for gaming, while a cheap USB 3.0 case might cap at 300–400 MB/s. Avoid running games from spinning USB hard drives if you can; their random-read weakness causes long loads and texture stutter.
Verify after a move
If a game acts oddly after relocating — missing textures, a crash on launch — right-click it in Steam and choose Properties → Installed Files → Verify integrity of game files. Steam re-checks every file against its manifest and re-downloads only what’s damaged, which is far faster than reinstalling. It’s also worth confirming the game still launches once from the new location before you delete any manual backups. One more tip: keep at least 15% free space on the destination drive, because a nearly full SSD slows down and leaves no room for future updates, which routinely add several gigabytes to big live-service titles.
Bottom line
Add the new drive under Settings → Storage, tick the games, and hit Move — Steam handles the rest without a re-download. Keep your most-played and open-world titles on the fastest NVMe you have, and offload the backlog to a larger, cheaper drive. It’s a five-minute habit that keeps your boot SSD healthy and your library organized.
