+In November 2021, Google launched a **[[https://developer.android.com/about/versions/11/privacy/storage|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:
-  * **the app has a full read/write access only to its PRIVATE FOLDER** in ///Android/data/// system directory (either in the internal storage or in the external storage - removable SD card)
+  * 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 ====
+==== Advantages of the private directory ====
-  * The app shows a better performance in **stability** and **responsiveness**
+  * App data is **secured** against access from other apps (possible attacks from malware etc.)
-  * Its 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.
-  * After the uninstallation, it leaves **no garbage** in the device storage.
 ==== Drawbacks ====
   * **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 Pro and Locus Map 4.
+  * **No use of other apps data** - it is no longer allowed to share one common directory between Locus Map Classic and Locus Map 4.
-  * **No custom sub-directories** - the app can read/write **vector maps** and **SRTM dat**a only in its private directory (only backup files can be stored elsewhere). Also, custom directories with **geotagged photos** are not supported - Locus can read from the **default system media directory** only.
+  * **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, all vector maps in ///Locus/mapsVector/// directory.
+  * **Disabled linking to maps from external folders** - all raster maps can be stored only in ///Locus/Maps/// directory or in ///Android/media/menion.android.locus/Maps/// directory, all vector maps in ///Locus/mapsVector/// directory or in ///Android/media/menion.android.locus/MapsVector/// directory.

 ===== What to do with it? =====
-The original default setting of the Locus Map main directory was in the root of the internal storage of the device. Plus, custom sub-directories could be set elsewhere in the internal or external storage (removable SD card), and external maps could be linked to the app from anywhere in the device storage.
-As this setup is no longer possible on Android 11+, we've prepared a few scenarios for **smooth and secure transfer of your data after the app update**:
-==== Update when a single Locus Map is installed ====
-When only a single app is installed on the device (the other Locus is not installed), the app update goes through the most simple and straightforward process.
-**[[manual:faq:single_update|How to do it >>]]**
-==== Update when both Locus Map 4 and Locus Map Pro are installed ====
-Older Android versions enabled sharing of the main app directory between Locus Map 4 and Locus Map Pro. This is no longer possible, each app can use only its own private folder. After the update, you have to decide whether to **use only one of the apps or both with the data size doubled**.
-**[[manual:faq:single_update_both_apps|How to do it >>]]**
-==== New installation on a device with old app data ====
-The main app directory used to remain at the root of the internal storage of the device when the app was uninstalled. You can transfer such data after a new Locus installation.
-**[[manual:faq:new_install_old_dir|How to do it >>]]**
-==== New installation when the other Locus is installed too ====
-The newly installed app can detect the other app on the device and offers to transfer its data.
-**[[manual:faq:new_install_second_app|How to do it >>]]**
-==== Custom subdirectories and external maps ====
+We've prepared a few scenarios for **smooth and secure transfer of your data after the app update**:
-Previously, Locus Map could work with data (maps, SRTM data, geotagged photos...) placed in subdirectories all over the device storage. As this is no longer possible, the data should be transferred to the private folder too.
