====== Update when both Locus Map 4 and Locus Map Classic are installed ======

----
Older Android versions enabled sharing of the main app directory between Locus Map 4 and Locus Map Classic. This is no longer possible due to the [[manual:faq:android_11_filesystem|recent changes in the Android file system]].

If you want to use your original data in updated Locus Map Classic after updating it together with Locus Map 4, please do the following:

  * Install and initialize the update of Locus Map Classic
  * Accept the offer to change its main directory:\\ {{ :manual:faq:page_force_move_root_info_lma.jpg?nolink |}}
  * **The app detects the other one** and warns of the possible loss of access to the data of the other app after the transfer\\ {{ :manual:faq:page_info_alt_app_exists_share_data.jpg?nolink |}}
  * Select one of the available **private folders** into which the data will be transferred
  * After the transfer, restart the updated app
===== What happens to the other app? =====
It is left without the original data but you can **copy the data from the updated app back**. 
  * **Update** the second app
  * Open //Settings > Miscellaneous > Default directories > Load Locus Map (Pro) data//
  * **Select and confirm the app directory** which content will be copied
  * Select **Copy** from the two options
