ACDSee uses a database to catalog images and media files on your computer. When you first install ACDSee, an empty database is created in a default location. ACDSee automatically adds file information and thumbnails to the database as you browse your folders.

Note: when browsing the database folder in Windows Explorer, you may not be able to see the “AppData” or “Local settings” folder – by default, these folders are "hidden" folders. You might have to change your settings in Windows Explorer, to make these folders visible. Proceed as follows:


  1. Click the ... (ellipsis button ) on the Tool Bar and choose Options.
  2. Click the View Tab.
  3. Select Show Hidden Files and Folders.
  4. Click Apply
  5. Click OK.
