All deleting should be done with caution - you need to decide whether you want to delete your geodata completely from your database (Library) or just from your work file (Place File).
When you delete items you can be selective and just delete them from a Place file or a Place folder or you can delete them from Library/Locations and they will be deleted from your database completely.
Delete waypoints, routes and tracks from your Place file, Place folder or Library
In your Place file or folder, select and highlight the items you want to delete in the Browser View area of the Content Panel.
Right click and choose to either Delete from Place File or Delete from Library. Please note: Delete from Library is a permanent deletion!
Aternatively, select an item (waypoint, route or track) on the Map View of the Content Panel, right click and Delete from Place File or Delete from Library.
Delete Place Files and Place Folders
Before deleting Place Files or Place Folders it is important to delete their contents from the Library if you want to delete the contents permanently from your Database. You should endeavour to keep your database clear of any unwanted data. To delete a Place File or Place Folder simply highlight the File or Folder in the Source List and click the backspace key.
