Rebuilding your Picasa database

General information

If you notice oddities in the appearance and placement of your photos within Picasa, you may need to rebuild your Picasa database. For each photo, the Picasa database keeps record of the following information:

  • Location of the files
  • Unsaved edits made to them
  • Album organization
  • Previews of the images
The rebuilding process won't affect your actual photos, but rather rebuilds the database that stores the information about your photos. However, if Picasa closes unexpectedly during the scan to recreate your photos database, your previous album organizations may be affected. We recommend that you back up your photos, edits, and album organization to CD/DVD or an external drive before starting the rebuilding process.
