Although it's not suggested to move program files to another drive, you still can make this task safely. The secret is to create a system image backup in advance.
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.
If possible, it's not suggested to move program files to a different drive. You can check if you are in the following situation and then decide if you have to do so.
Situation 1: low disk space warning pop up several times
As time goes by, the system partition may run out of space owing to increasing programs, and the PC may slow down as well. The situation could be more severe if you install a large amount of software on the computer.
In this case, if you don't want to uninstall them, try to move program files and program files (x86) from C drive to D drive or other partition with enough space, then save the newly installed software to new partition instead of C drive.
Situation 2: SSD does not have enough space
Nowadays, it's not rare to migrate OS to smaller SSD and use it as storage. But the problem is SSD can be fulfilled quickly if you install multiple programs on it. Thus, some users may want to free up disk space of SSD or directly move program files and program files (x86) from SSD to HDD. In this case, you have enjoyed both advantages of SSDs and HDDs.
If you are in one or two situations above, you may want to use a relatively safe method. Then, how to make it easily? You can choose to make a system image backup (if you want) with a free backup software, AOMEI Backupper Standard, for example. Thus, you can get the PC back to normal without downtime.
Afterward, you can feel free to try the following 4 methods to move program files to different drive, namely using Registry, mklink, Move, or App mover.
๐ Method 1: Migrate program files to another drive using Registry Editor ๐ Method 2: Move program files to different drive using mklink ๐ Method 3: Move installed program to another drive using “Move” feature ๐ Method 4: Transfer program files from C to D with App Mover๐ฅ
The first method is to change program file location from C to D or other partition and works at the moment of clean install Windows. In the beginning, you need to do two things in the following:
Then, open the Registry Editor and change program location from C to SSD.
Step 1. Press “Win + R”to summon the Run window, then type Regedit.exe.
Step 2. Find the following path on Registry Editor and change 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
The second method is to create a symbolic link using Command Prompt. A symbolic link is a bit like the shortcuts to programs, folders and websites which 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 “C: \Program Files” folder to “D: \Program Files”.
Step 2. Type cmd in the search box, click it and run as administrator.
Step 3. Copy and paste the following command and hit Enter. Type mklink in the command prompt window and learn 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.
Also, you can use mklink /J link target (called hard link) to makes the files or folders appears as if it actually exist at the location of the symbolic link. Based on the above example, you can type as mklink /J “Program Files” “D: Program Files”.
If you want to delete the old program files, you can use “mklink /j” link together with the full drive letter and path of the old and new locations of the program files.
This feature not only move program from C drive to D drive, but also can relocate program files. Just tri it yourself.
Step 1. Go to start menu > Settings > System > Apps & features, then you will see a list 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.
