If you have the original Memory-Map app installed on an Android or iOS device, and you install the new Memory-Map for All app, you might assume that it will be able to access maps and data already installed in the old app. However, this is not the case. A fundamental feature of both Android and iOS is that apps are not able to access data belonging to another app.
The only ways to add maps to Memory-Map for All are:
- Download them (using My Online Maps or Digital Map Store)
- Copy them in using Map Storage > Copy Maps From
- The iOS version also supports iTunes/Finder file transfer. However, we don't provide technical support for using this feature. If you know how to use iTunes/Finder file transfer and you know what files to copy, etc, that's great. If not use one of the methods above.
On Android, the original Memory-Map app allows you to manually copy maps into the Download folder or onto the SD card. Due to Android's "Scoped Storage" rules, this is not permitted for any new apps. Memory-Map for All does not have any access to data or maps outside the app, except when explicitly importing or exporting files. If you have maps on a public area of the device, such as the Download/Memory-Map folder, you can use Map Storage > Copy Maps From to make a copy of those maps into the private storage area inside the app. If you have an SD Card, set up Memory-Map for All to use the card (under Map Storage), then use Copy Maps From. This will make a copy of the selected map folders in the public area and place them in a private area of the SD Card that can't be accessed by other apps.

In summary, the original app can access public areas because it was developed before the scoped storage policy came into force. Memory-Map for All requires a separate copy of all maps.
