How to Move Honkai Star Rail to Another Drive

That red storage bar isn’t decorative—it’s screaming. Every HoYoverse patch drops gigabytes of voice lines, high-fidelity textures, and event assets that devour your primary drive faster than you can clear Memory of Chaos floors. Moving to a larger drive or faster SSD sounds sensible until you realize redownloading 30GB+ on a throttled internet means losing an entire evening to progress bars instead of farming relics.

Stop reaching for the uninstall button. Redownloading is what happens when you don’t know better, and you’re about to learn the surgical file transfer method that tricks launchers, preserves every byte, and gets you back on the Astral Express in minutes instead of hours.

Why Dragging Folders Breaks Everything

Most players assume they can cut the installation folder, paste it somewhere new, and click their desktop shortcut like nothing changed. That approach guarantees disaster. Windows Registry entries and launcher configuration files still point to the original location, meaning the launcher panics when it can’t find the expected directory structure. Instead of recognizing your moved files, it assumes the game vanished and forces a full redownload from HoYoverse servers.

The launcher doesn’t automatically update its internal map when you relocate files manually. You need to either use built-in relocation features or execute precise workarounds that force the software to acknowledge the new path. Skip these steps, and you’ll watch your bandwidth evaporate while the launcher downloads files you already own sitting three folders away on a different drive.

HoYoPlay Launcher Method Handles Official Installations

HoYoverse’s HoYoPlay launcher includes a “Locate Game” feature designed specifically for migration scenarios. This method works cleanly for most users and avoids registry editing or fake installation tricks.

Step-by-step execution:

1. Terminate all processes: Close Honkai Star Rail and HoYoPlay completely. Open Task Manager and verify no background instances of StarRail.exe or HoYoPlay.exe remain active.
2. Execute the transfer: Navigate to your current installation folder (typically C:\Program Files\Honkai Star Rail). Cut the entire directory and paste it into your destination drive location (example: D:\Games\Honkai Star Rail).
3. Launch and trigger detection: Open HoYoPlay. The launcher will display “Get Game” or “Download” because it lost track of your files. This is expected behavior.
4. Activate the locate function: Find the “Locate Game” option near the download button or inside the settings menu (three-line icon). Click it to open a file explorer window.
5. Target the new location: Navigate to your destination folder containing StarRail.exe and select it.
6. Verify integrity: HoYoPlay runs a quick file verification scan. Once complete, the button changes to “Launch” and you’re operational.

Method	Data Loss Risk	Time Required	Bandwidth Used
Uninstall/Reinstall	High (settings reset)	2-4 hours	30GB+ download
Locate Game Feature	None	5-10 minutes	0 MB (verification only)
Epic Games Workaround	Low (if executed correctly)	15-20 minutes	~100 MB verification

Epic Games Launcher Demands The Fake Install Workaround

Epic Games Store doesn’t offer a “Locate Game” button, making migration more complex. The workaround involves tricking Epic into thinking it’s downloading the game fresh, then swapping your existing files into the partial installation directory before verification completes.

The fake install protocol:

1. Save your installation: Change the name of your existing Honkai Star Rail folder to a temporary one, e.g., HonkaiStarRail_Backup.
2. Delete the library record: Launcher: Open Epic Games Launcher, right-click Honkai Star Rail and click Uninstall. This is just to eliminate the library association, as you really renamed the folder–you have not yet lost the actual files.
3. Installation Check: Click on install and choose your new drive where you want to install it.
4. Break at 1 percent mark: Wait until the download is between 10-20 seconds, and the download has reached 1-2 percent done. Stop the download, and restart Epic Games Launcher (end via Task Manager to make sure it is shut).
5. Execute the swap: Navigate to your new drive. Delete the partial files Epic just created (the 1-2% placeholder). Copy everything from your HonkaiStarRail_Backup folder into this now-empty directory.
6. Resume and verify: Reopen the Epic Games Launcher and resume the download. Instead of downloading 30GB, Epic detects your existing files, switches to “Verifying,” and completes within seconds.

Config File Editing Bypasses Stubborn Launchers

When the “Locate Game” button greys out, or UI bugs prevent normal relocation, manual config editing provides total control. This method requires opening the game’s configuration file and directly updating the installation path.

Navigate to your moved installation folder and locate config.ini. Open it with Notepad. Find the line:

game_install_path=C:/Program Files/Star Rail

This path still references your old location. Replace it with your new drive path:

game_install_path=D:/Games/Star Rail

Check for a game_version entry while editing. If missing, the launcher might attempt unnecessary repairs. Ensure it matches the current live version (example: game_version=2.3.0). Save the file and launch HoYoPlay—it should recognize the directory immediately without prompting.

Common Transfer Failures And Their Solutions

Even perfect execution encounters occasional technical glitches. Two errors dominate failed migration attempts when you move Honkai Star Rail to another drive.

Verification Failed Loop:

The launcher endlessly verifies without completing. This indicates incorrect folder nesting. HoYoPlay expects the structure Honkai Star Rail/Games/StarRail.exe. If you accidentally created Honkai Star Rail/Honkai Star Rail/Games/StarRail.exe (double nesting), the path breaks. Verify your folder hierarchy matches the launcher’s expectations—config.ini should sit in the root directory with the executable inside the Games subfolder.

Insufficient Space False Flag:

Your destination drive shows 500GB free space, but the launcher claims “Insufficient Space” during verification. This happens because verification unpacks temporary assets to your system’s Temp folder (%temp%), which resides on your C: drive, regardless of installation location.

Error Type	Root Cause	Fix
Verification Loop	Incorrect folder nesting	Flatten directory structure to match launcher expectations
Insufficient Space (D: has space)	C: drive Temp folder full	Edit config.ini with the exact new file path
Launcher Won’t Start	Config path mismatch	Edit config.ini with exact new file path

FAQ

Does manually moving game files and using Locate Game trigger anti-cheat bans or account restrictions?
No. Official relocation features are supported functionality. Bans only occur from modifying game executables or using symlinks that confuse integrity checks.

Why does the launcher redownload everything even after I correctly moved all files to the new drive?
Folder structure mismatch. The launcher needs StarRail.exe at the exact path you specified. Nested folders or missing subfolders cause path detection failures.

Can I launch the game directly from StarRail.exe without opening the launcher after moving it?

Technically, yes, but you’ll miss hotfix patches. Version mismatches between client and server cause login errors requiring launcher verification anyway.

Moving files saves data, but if you have no time for this headache, you can skip the technical hassle entirely by finding an HSR account for sale on U7BUY. Now your game loads instantly; then, how about you can speed up your progression with a Honkai Star Rail topup from U7BUY.
