By default, the index data files are stored in a per-user path like this: 

"C:\Documents and Settings\**user name**\Local Settings\Application Data\CopernicDesktopSearch."


"C:\Users\**user name**\Local\Copernic\DesktopSearch."

This ensures that all users of your computer have their own personal index stored in a non-shared location. If you want to move your index data files, you can do this :

  1. Open tools menu
  2. Options
  3. In "indexing and performance" tab
  4. Change index location

You must restart Copernic Desktop Search after changing index location and an update of your index will be needed.
