Previously, Locus Map could work with data (maps, SRTM data, geotagged photos…) placed in subdirectories all over the device storage. This is no longer possible due to the recent changes in the Android file system - the custom data have to be transferred to the app private folder.

If you had this data stored in custom sub-directories, Locus Map detects them and offers to merge them into the main app directory during the app data transfer:

After the app data transfer, you can place the sub-directories to the private directory on the removable SD card if you need to save the internal storage space:

You lose access to the data via Locus. The data will remain in the device storage though.

The only sub-directory that can be placed out of the main app directory.

Linking of the maps from external directories is also no longer supported. The external maps can be used only within the default /Locus/Maps/ directory.

Unfortunately, it is not technically possible to include external maps into the automatic transfer of the app data. You have to move the maps to /Locus/Maps/ directory manually via the system file manager.

Locus Map on Android 11+ can access only the default system media folder (usually /storage/emulated/0/DCIM/)

If you want to display photos from custom directories on the map, you have to move/copy them to this default media folder via a system file manager.
