Mobile inner memory capacity is still an issue for many Android users. It is still too small and soon after starting using your new device the memory is full. External SD card has always served as a solution of this problem.

By default, Locus stores/downloads raster maps (consisting of raster images - png tiles) in Locus/maps directory in the inner storage of your device.

• open Locus settings > Miscellaneous > Default directories > Set custom subdirectories
• tap Set 'maps' directory
• select Private folder on SD card and confirm
• contents of the original Maps folder are moved to the new storage and all future raster maps downloads will be directed into it. The app needs restart after this operation.

This option requires All files access system permission

• create a new folder on your external SD card, e.g. Maps_external, with a file manager
• move whole content of the original Locus/maps directory there
• go to Locus > Map manager > Offline tab
• tap and then External maps
  
• find your new “Maps_external” folder and confirm blue button
  
• your “Maps_external” folder appears in Locus > Maps manager > Offline tab

LoMaps or other vector maps are stored by default in /Locus/mapsVector/ directory.

• open Locus settings > Miscellaneous > Default directories > Set custom subdirectories
• tap Set 'mapsVector' directory
• select Private folder on SD card or Custom selection and confirm
• contents of the original MapsVector folder are moved to the new storage and all future vector maps downloads will be directed into it. The app needs restart after this operation.

The procedure is the same is in the case of raster maps. With one exception - external themes of vector maps (e.g. Elevate from OAM) must remain in the default /Locus/MapsVector/_themes/ directory.
