Practical Ways to Move Microsoft Office to Another Drive

With the usage of computer, we may run out of drives’ space. We have to move large programs to another drive or clean up unimportant files. Especially for Microsoft Office, it occupies a large space on computer. When you purchase a new drive, it’s time to migrate MS Office to release your C: drive. However, it’s not an easy task to move Office without reinstalling it. You can just copy and paste the Office program to another drive directly. Hence, I collect a few useful methods for you to move MS Office to another drive with ease in this article.

However, this feature only specifies for Windows 10 apps installed by default, like Movies, Photos, Calculator, etc. As for the apps installed from other sources, it’s unavailable. But there are still ways to reach this am. Just follow below two methods.

Part 2. Move pre-installed MS Office to another drive through creating a junction

By default, MS Office is installed in C: drive. Typically, the installation path is C:Program Files (x86)Microsoft Office. Certainly, you may install the programs on another path, but it will not affect the usage of this method.

You can create a junction to move MS Office form one drive to another. First, open Command Prompt as Administrator and then run below commands in the Command window. Be careful that here takes MS Office installed on 64-bit Windows as an instance, so the program location may vary. Change it as needed.

First backup Office folder (optional):

ren “C:Program Files (x86)Microsoft Office” “Microsoft Office.bak”

Then copy all the files in this folder to the new drive with permissions intact:

robocopy “C:Program Files (x86)Microsoft Office.bak” “D:Microsoft Office” /E /ZB /DCOPY:T /COPYALL /R:1 /W:1 /V

Next, create the junction between the old location and new location:

mklink /J “C:Program Files (x86)Microsoft Office” “D:Microsoft Office”

Finally, copy the permissions to the junction:

robocopy “D:Microsoft Office” “C:Program Files (x86)Microsoft Office” /E /COPY:SOU /xo /xn /xc /xx

Hereto, you succeed to create a junction to the new drive. However, it’s better to test the program to ensure it’s working. In addition, once the program works fine in the new drive, just delete the backup you made previously.

Bonus. How to change installation path of Office 365

You can make some modifications in the Registry to change install directory.
