Due to the recent changes in the Android file system, it is necessary to transfer the app data to the private folder in /Android/data/ directory after the app update. When only a single app is installed on the device (the other Locus is not installed), the data transfer is simple:

• one app (Locus Map Pro 3.55.x) is installed
• download and install Locus Map Pro 3.56
• during the app initialization, you are notified of the app directory /Locus/ stored in the unsupported part of the internal storage:
  
• after accepting it, you can select the private folder into which the data will be transferred - either in the internal storage or on the external SD card
• you can also merge data from your custom-defined subdirectories:
  
• Locus smoothly transfers all the original data into its private folder
• the process may take a few minutes depending on the size of your data
• after the app restarts, all is done and working as before

• you can go on using the app as before
• but you are notified of the app data transfer at each next start of the app
• you can move the original data any time also from the app main menu:
  
  or from settings > miscellaneous > default directory.
