When you add media to a POI the file is saved in the PDB file. For example you attach an audio file that is 500KB, your user.pdb file is now at least 500KB. When you remove the media file from your POI your user.pdb file is still at least 500KB. Using the Free POI Database Space option shrinks the database to the size it was before adding the audio file. This task is not executed automatically as it could take a while. If you add/remove media files it is a good idea to select the Free POI Database Space option on a regular basis. The Free POI Database Space option is located in the Advanced GPS options menu. From within ?Sendero GPS, press O for GPS options. Scroll to Advanced GPS options and press ENTER. Finally scroll to the "free database space for user POIs and favorites" and press ENTER. .
