Quick Guide: Move Program Files to Another Drive Windows 10

Can I move program files to another drive? Is it safe?

You may know most programs are installed in C: drive by default, and usually, Program Files for 64-bit programs and Program Files (x86) for 32-bit programs. Both of them are hard-wired into Windows and things can go wrong if they are not where they’re supposed to be. 

If you drag them to another location directly, most of the programs on Windows 10 or other systems may stop working or do not respond correctly. Thus, it's not safe to move program files to another drive. 

However, sometimes, you need to move program files to a different drive, e.g., move program files from C drive to D drive or or SSD to HDD, though it's not suggested. 

• Insufficient space on the C drive, repeatedly receiving low disk space warnings
• You migrate OS to smaller SSD, but the space quickly fills up.

The situation could be more severe if you install a large amount of software on the computer. 

How to move program files to another drive safely 

If you are in one or two situations above, you may want to move program files to another drive, but not causing your program to stop working or not respond. In this case, the best method is to make a system image backup first. Free backup software, AOMEI Backupper Standard, is recommended, which can help you restore Windows 10 to new hard drive or SSD without any downtime.

Afterward, you can feel free to try the following 4 methods to move program files to a different drive, namely using Registry, mklink, Move, or App mover.

👉 Method 1: Migrate program files to another drive using Registry Editor
👉 Method 2: Move program files to different drive using mklink
👉 Method 3: Move installed program to another drive using “Move” feature
👉 Method 4: Transfer program files from C to D with App Mover🔥

Method 1: Migrate program files to another drive using Registry Editor

The first method is to change program file location from C to D or another partition and work at the moment of a clean install of Windows. In the beginning, you need to do two things in the following: 

Create a folder named Program files (x86) on another drive (eg: D: drive)

Copy "Program Files" and "Program Files (x86)" directories to the new location first. Just run CMD as administrator, type the following command prompt, and hit Enter.
     >> Robocopy "C:\Program Files" "D:\Program Files" /mir
     >> Robocopy "C:\Program Files (x86)" "D:\Program Files (x86)" /mir

Then, open the Registry Editor and change the program location from C to D. 

Step 1. Press “Win + R” to summon the Run window, then type Regedit.exe.

Step 2. Find the following path in the Registry Editor and change the drive letter from C: to D:

To Windows 7/8/8.1:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

To Windows 10:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion

Method 2: Move program files to a different drive using mklink (for technicians)

The second method is to create a symbolic link using the Command Prompt. A symbolic link is a bit like the shortcuts to programs, folders, and websites that attach to the desktop. To put it simply, when Windows or any program tries to access the folder, the symbolic link redirects it to the new location.

Learn how to move program files from C to D securely as follows. Also, this applies to moving program files from SSD to HDD.

Step 1. Move the “C: \Program Files” folder to “D: \Program Files”.

Step 2. Type cmd in the search box, click it, and select run as administrator.

Step 3. Copy and paste the following command and hit Enter. Type mklink in the command prompt window and learn the necessary parameters if you are not familiar with this command. 

mklink /D “Program Files” “D: Program Files”

“Program Files” is the name of your new symbolic link name.
“D: Program Files” is the path your new link refers to.

Then, you can use the C:\Programs Files as the default install path, but all the installed files will be stored in D:\Program Files.  

Method 3: Move installed program to another drive using “Move” feature 

This feature not only move program from C drive to D drive, but also can relocate program files. Just try it yourself.

Step 1. Go to start menu > Settings > System > Apps & features, then you will see a list of programs.

Step 2. Select an app and hit the Move option under the specified app, and then select a location on another drive.

Step 3. Click Move again.

Step 4. Repeat Step 2 and Step 3 until the last program is moved to a new drive.

Method 4: Transfer program files from C to D with App Mover (One-click & newbie-friendly)

Besides, you can still try AOMEI Partition Assistant to move your program and program files from C to D or SSD to HDD safely. It's a disk management software for Windows 11/10/8/7/XP/Vista.  Please download it on your computer and then install it. 

 Step 1. Launch AOMEI Partition Assistant Professional. Then, click All Tools and select App Mover under the Other Tools tab.

Step 2. Select the C drive and hit "Next".

Step 3. Tick the name of the applications you want to move and choose the D drive to receive it. 

Step 4. Click on Move and then OK, it will start the program files transfer process.

Except for the entire program files folder, some users just want to move the Steam games, just like the following case. 

"I'm on Windows 10, and I need to move that folder to my D drive. I have been told that copy-pasting it won't work, and I will need to delete and redownload it. This is a problem because the file is over 36 GB, and most of them are my Steam games. Is there any other way to do this?"

Here's how to move Steam games to another drive: 

• Go to the location of your Steam library. If you aren’t sure, you can check this information at the Properties of the Steam shortcut.
• Shut down the Steam games, then copy and paste the entire Steam Folder to the new location, here is D:\Steam\ folder. 
• Wait until the process completes, you can start to rerun Steam.exe from the new location. 

Before rerunning the Steam.exe, it's suggested to reinstall it to update all your shortcuts. Download the installer from steampowered.com and select the new location as the destination folder, here is D:\Steam\folder. Lastly, click Install to reinstall the Steam.exe.
