Using Locus Map on Android 11+ file system

What is this all about?

In November 2021, Google launched a new file management system in Android 11 and the following versions, bringing a major change to the way Locus Map and other applications handle their data:

  • by default, the app has a full read/write access to its PRIVATE FOLDER in /Android/data/ system directory (either in the internal storage or in the external storage - removable SD card)

Advantages of the private directory

  • App data is secured against access from other apps (possible attacks from malware etc.)
  • After the uninstallation, the app leaves no garbage in the device storage.


  • All app data is deleted upon uninstall - the majority of devices show a warning prompt with the option to retain the app data in the storage. But especially Chinese products erase the data without an option of restoring.
  • No use of other apps data - it is no longer allowed to share one common directory between Locus Map Classic and Locus Map 4.
  • Limited custom sub-directories - the app can read/write data only in its private directory or in /Android/media/ directory. Only backup files can be stored elsewhere. Also, custom directories with geotagged photos are not supported - Locus Map can only read from the default system media directory or /Android/Media/ sector.
  • Disabled linking to maps from external folders - all raster maps can be stored only in /Locus/Maps/ directory or in /Android/media/ directory, all vector maps in /Locus/mapsVector/ directory or in /Android/media/ directory.

As a precaution before the update to Locus Map 4.5.x or Locus Map Classic 3.56.x we urgently recommend:
