====== Export / Import Terrain Files ======
I used some custom formats for files used to import or export tile data. Generally, there are three file formats used for exporting/importing L2 terrain data and only one for exporting elevation data while in [[manuals:terraineditor:reference:temain:home#L0/ELV Mode|L0/ELV mode]].

The way the data are read at all cases is the same and can be seen in the following picture:

{{:manuals:terraineditor:reference:file_formats_reference:export_grid_0.jpg|}}

While the map's lower-left point is the starting point (0,0), the X axis is horizontally and Y axis is vertically. In an export/import area the data order starts from the lower-left tile of this area (depicted with a dot in the picture) and the order the data are stored is row by row (represented by the arrows).

===== L2 Export/Import Files =====
The file types available are:
  *''(*.exp)'': This contains only tile offset values (tile numbering) of the exported/importing tiles.
  *''(*.xpe)'': This contains tile offset values (tile numbering) and elevation data of the exported/importing tiles.
  *''(*.xpf)'': This contains all tile values (tile offset, elevation, PAL offset, X1 and X2) of the exported/importing tiles.

The format of these files are:
