Import is used when you want to work with tracks and/or points from outside of Locus - websites, apps, add-ons, etc.
A file manager opens with tabs displaying available drives - local, Dropbox (if installed), Google Drive (if installed) and a field to fill in a URL of a remote file. Importable files are in full color and are clickable:
After selecting the file Locus Map analyses it and modifies the import dialog according to the content - the dialog can process points or tracks or both of them at once:
After pushing the Import button the imported points appear in the selected folder of the Points manager, respectively tracks in the Tracks manager. Depending on whether the option Display on the map after import is checked the imported data appear on the map as well.
