Steps to Redirect Lightroom Desktop Cache

1. Close Lightroom Desktop: Ensure that Lightroom Desktop is not running.

2. Open Command Prompt as Administrator:

   • Click on the Start menu.

   • Type cmd in the search bar.

   • Right-click on Command Prompt and select Run as administrator.

3. Execute the Following Commands:
   Replace <YourUsername> with your actual Windows username.

   cmd

   CopyEdit

   cd "C:\Users\<YourUsername>\AppData\Local\Adobe\Lightroom CC" ren Data Data_backup mklink /D Data "W:\LightroomCache"

   Explanation:

   • cd navigates to the Lightroom CC directory.

   • ren renames the existing Data folder to Data_backup as a precaution.

   • mklink /D creates a symbolic link named Data that points to W:\LightroomCache.

4. Verify the Symbolic Link:

   • Navigate to C:\Users\<YourUsername>\AppData\Local\Adobe\Lightroom CC.

   • You should see a folder named Data with a shortcut icon, indicating it's a symbolic link.

5. Restart Lightroom Desktop:

   • Open Lightroom Desktop. It will now use the cache located at W:\LightroomCache.Adobe Help Center

Note: If everything works as expected, you can delete the Data_backup folder to free up space.
