xBase files have no concept of a georeferencing system, and the produced attribute layer will be marked as being in the METRE georeferencing system.
xBase files are written from a vector layer, but ignore any vertex, or georeferencing information, writing only the attribute information.
All attribute types except CountedInt are supported for write in xBase files; however, all fields are assign a maximum width when written based on the field formatting information. This means there is an upper limit on the size of string that can be written to a .dbf file, though this limit is established according to the field format width in the source layer.
Only one vector layer can be written to a .dbf file, and no other datatypes can be written.
Export of xBase files is supported. xBase files are exported with a type of "DBF".
