How to manage PI files???

I don't use Base camp so I can't comment on its use, but neither Poi loader or file explorer will show you what is on the gps for individual files. Poi loader installs the poi files and converts it to 1 file with a gpi extension.

I would use windows explorer and check to see if you have multiple gpi files installed for the same poi files.

I did that - I still cannot find duplicates.
Is there another file that they may be hiding?

This would be the way to determine your Custom POI files. You are looking for .gpi files in the POI folder.

If there are two with the same name, I would suspect that you would want to delete the one with the oldest timestamp.

Best guess is you have multiple GPI files and they have duplicate files.

Did you load these on an SD card? If so, when you install the SD into the GPS it will ask if you want to also load onto the GPS.

If you purposely or accidentally said Yes, you might get duplicates. Remove the SD and see if you still get duplicates.

I went to Windows Explorer - made sure I could find hidden files -and duplicate files still to not show.

Run poi loader again and delete ALL .gpi files. Then I would install your files again with poi loader.

YAY! That worked. Thank you.

Thanks for letting us know.
Evidently you had duplicate .gpi files
