Auto-Analyzer in Elements Organizer automatically detects and tags the following when analyzing media.
Auto analyzer is run as soon as you import media into Elements Organizer. When there is considerable media to analyze, run auto analyzer during the system’s idle time.
You can add additional tags manually after auto analysis. However, the Auto Analyzer tags can be removed from media, but you cannot edit/delete them from the smart tags list
In case you do not wish to run it just disable it from
Hope it helps.
