-====== How to change the location of stored data ? ====== 
  
-The application ​needs to store various ​data on the user device, including:​ +====== Where does the application store its data? ====== 
-  * Saved landmarks ​(waypointstracks, etc.)+\\ 
-  * Stored map areas of on-demand mapsso they can be used offline+The application ​folder is the unique folder used by the application ​to store all its data on the user device, including:​ 
-  * Various ​configuration and cache data, including added maps, favorite map sets, etc.+  * Stored maps for off-line use; 
 +  * User landmarks, ​when using the default landmarks folder
 +  * Imported and exported landmarksdetails or map images; 
 +  * Pictures ​used in waypoints
 +  * Various ​technical ​data.
  
-{{:​icon_help.png?​nolink}} For devices running Android versions less that 4.4, the application ​will try to detect ​and use by default ​the external SD memory ​card if any, otherwise the internal device memory will be used. For devices running Android ​version ​4.4 and more, the application will use by default the internal ​device memory.+This folder is automatically chosen during ​the first application ​start, ​and is usually located on the external SD card (if available) for devices running Android ​lower than 4.4, or on the device memory ​for Android 4.4 and after (SD card storage behavior has considerably changed since then).
  
-To modify ​the local storage location+Inside ​the application folder, you'll find the following sub-folders
-  * Click on the main menu icon {{:​icon_01.png?​nolink}} and then on "''​**Settings**''​" {{:icon_02.png?​nolink}}+  * ''​**/cache/**''​, where the application stores downloaded data like [[en:help:​maps#​on-demand_maps|on-demand maps]]

-  * Choose one of the available choice {{:​icon_04.png?​nolink}},​ either on the internal "''​**Device storage**''​"or on the external "''​**SD Card**''​". Multiple choices can be available for a particular storageyou can check the "''​**Application path**''"​ {{:​icon_05.png?​nolink}} for each choices as well as the current space already used+  * ''​**/landmarks/**'', ​where the application stores (by default) the landmarks you create (waypoints, routes, tracks, areas); 
-  * Click on the "''​**Ok**''​" {{:​icon_06.png?​nolink}} button to validate ​the change; +  * ''​**/logs/**'', ​where the application store its technical logs
-  * Restart the application.+  * ''​**/pictures/**''​, where the application stores pictures associated with picture waypoints (on some devices these pictures are saved in the device common media folder);
  
-{{:​icon_help.png?​nolink}} If you want to use a particular location which is not listed, you can click on "''​**More**''"​ {{:​icon_07.png?​nolink}} button and manually type any location path. Note that the application name will be appended to the entered path;+\\

-As of Android 4.4, the memory management has been modified+===== How to change ​the application folder? ===== 
-  * The device memory is called ​"//Primary external memory//"​. ​This is the main storage memory, used by default by the applicationThis memory is usually quite large (up to hundred of GB)+\\ 
-  * The SD card memory (available on some devices only) is called ​"//Secondary external memory//"​. ​This space is not freely editable by applications anymore, only a specific folder per application ​can be used, as explained below.+To modify the storage location
 +  * Click on the main menu icon {{:​icon_01.png?​nolink}};​

 +{{:​icon_help.png?​nolink}} Be careful if you choose a storage location within the ''"​**/​Android/​data/​**"''​ folder as Android will delete it when you un-install the application.
  
-==== Setting up the storage on the SD card ====+{{:​icon_help.png?​nolink}} If you see a small locker {{:​icon_06.png?​nolink}} icon, it means that the application isn't able to write in this location, and so it cannot be used. Check the troubleshooting section below for more details.
  
-As explained above, only a particular folder on the SD card is editable by the application on devices with Android 4.4 or more. This folder is: +{{ :en:​help:​settings:​change-storage.jpg?nolink }}
-  * **''/​Android/​data/​net.psyberia.offlinemaps/​files/''​** for the ad supported version; +
-  * **''/​Android/​data/​net.psyberia.offlinemapsplus/​files''​** for the + (paid) version.+
  
-{{:​icon_help.png?​nolink}} This folder is created by the application,​ you mustn'​t create it manually.+\\
  
-To set up the storage on this folder, ​just process as explained above and choose ​the entry with this particular application path.+==== Storage on the external SD card troubleshooting ==== 
 +\\ 
 +In Android 4.4 and above, the memory management has been modified: 
 +  * The device internal memory is called "//​Primary external memory//"​. This is the main storage ​memory, used by default by the application. This memory is usually quite large (up to hundred of GB); 
 +  * The SD card external memory (available ​on some devices only) is called "//​Secondary external memory//"​. This space is not freely editable by applications anymore, only a specific ​folder ​per application can be usedthat's why you may only have one location available on the external SD card.
  
-{{:​icon_help.png?​nolink}} Note that when uninstalling ​the application, this folder will be automatically deleted by Android ​and all the stored data (landmarks, stored map areas, ...will be lost.+In Android 6.0 and above, you can now grant the application ​the right to write on the external SD card from the Android ​settings ​("​Applications"​ section).
  
-==== Re-using data stored before ​an Android ​4.4 upgrade ====+If no storage location choices at all are available on the external SD card: 
 +  * Be sure that your device is not currently plugged to a computer ​using an USB cable; 
 +  * Be sure that the SD card is not currently being checked for errors (usually happens after starting the device or removing the USB cable); 
 +  * If you have Android ​6.0 or above, you must grant the application to write on the external memory from the Android settings ("​Applications"​ section), [[http://​www.howtogeek.com/​230683/​how-to-manage-app-permissions-on-android-6.0/​|see more details here]]; 
 +  * Try to restart the device; 
 +  * Try to un-install and re-install the application (be careful if you have stored data you want to keep); 
 +  * In the Android settings ("​Storage"​ section), try to un-mount your SD card and check it for errors.

-{{:​icon_help.png?​nolink}} Do not use your Android file manager to move the data, it will leave it read-only in the new location.+
  
-{{:​icon_help.png?​nolink}} A similar method can be used to use data stored using the free version with the paid one, the data must be moved from "''​**/​Android/​data/​net.psyberia.offlinemaps/​files/​**''"​ to "''​**/​Android/​data/​net.psyberia.offlinemapsplus/​files/​**''"​ using your computer'​s file explorer.
