I have a large number of Garmin custom maps, but I don't seem to be able to import them properly into Basecamp. I have set up a folder called Iceland kmz files. If I then File>Import into Iceland kmz files, the files come into Basecamp, but not directly into the folder. I have then to drag them one by one up into the folder. Here is a screenshot having dragged two kmz files into the folder.
I subsequently dragged all these kmz files (which have an odd icon that I don't understand: like a list icon but with a small white page lower right) into the Iceland kmz files. I then did another File>Import. The file appeared at the bottom of the list (VarmahlidGPS.kmz) - but all the other kmz files disappeared from the Iceland kmz files folder.
However, if I looked at the total contents of my library (BaseCamp190607), they are apparently still there, along with repeat versions from previous Import attempts, and with a different icon.
The same thing happens if I try to import the kmz files into a list. They don't import to the list; they have to be dragged there; and they disappear if another kmz file is imported.
Clearly, I don't understand what is going on. Can anyone enlighten me?
Thanks!
