Can I transfer my PC games from C drive to D drive?

“Even as a game enthusiast, I have too many games on C drive in my windows10. Now, the space of the C drive is going to run out and many games are stuck frequently, the game screen is also lagging..., but there is still plenty of free space on the D drive, can I transfer my PC games from the C drive to D drive? Does that cause any other problems? Thanks!”


What is the problem if there are too many games installed on the c drive in Win10? First of all, most of the C drives are installed with the system. When the capacity is exhausted by games and other software, the read and write performance will decrease.

Under heavy load (game model loading, etc.), normal service will be seriously affected. What causes the write amplification is that the drive capacity is largely occupied by the game so that the computer slows down. Therefore, some may choose to transfer some games from one C hard drive to another to keep a smooth performance.

Three options to move games from C drive to D drive

What methods are generally adopted to migrate the game from C drive to D drive? For platforms such as Steam, EA, GOG Galaxy, and We game, you can use platform management to migrate the game, like many players also search how to move a Steam game to another drive with Steam’s inbuilt feature.

Non-platform games or bad platforms (origin, etc.) need to migrate the game body, save, and rewrite the registry, which is more difficult for novices. It’s utterly cruel for most game players to forgo their games by dint of the triviality that the space of C drive is almost full.

Thus, here we show three alternatives that may help you solve your troubles.

1. Move games from C drive to D drive via Registry

The registry contains information used by programs and Windows itself, which assists the operating system in managing your computer. You can relocate installed apps by changing the registry.

Step 1. Create a new folder named "Program Files (86)" in the C drive or another drive.

Create Program Files86

Step 2. Copy "Program Files" and "Program Files (x86)" directories to the new folder.

Copy Program Files to New Folder

Step 3. Insert “CMD” in the search bar, right-click it, select “Run as administrator”.

CMD Administrator

Step 4. Insert the following commands and press “Enter”.

• Robocopy" C:\ Program Files" " X:\ Program Files" / mir
• Robocopy" C:\ Program Files(x86)" " X:\ Program Files(x86)" / mir

Tip: “X” is the drive letter of the created file.

Step 5. Press “Win + R”, then type “Regedit.exe”.

Step 6. Find the folder path and change the C to another drive.

For Windows 10: HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows \ CurrentVersion

For Windows 7/8/8.1: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion

Warning: If you misapply the registry, your system may crash.

2. Unload and reload in D drive while keep and move data files

Many players also choose an orthodox approach to transfer their games, although it will take a lot of time.

Step 1. Unload and reload the game but install on D drive.

Step 2. Find those files on C drive, then cut and paste them into the game folder on D drive.

3. Transfer games from C drive to D drive via a workable app mover

If both ways can’t help you to transfer games from C drive to D drive without run failure, a convenient&professional application mover for Windows10/8.1/8/7/Vista/XP – AOMEI Partition Assistant Professional is a nice choice.
