Main Window - Thumbnail | Scan System...                    Alt+F3

 

 

Use this menu selection to select the categories of drives you want to scan and thumbnail.

 

To start the scan click OK and ThumbsPlus will scan each area selected for files to be thumbnailed.

 

Note: If the Rescan (make all thumbnails) option is unchecked, ThumbsPlus will only create thumbnails for those files that do not already have a thumbnmail stored in the database.
