How do I create a .zip file?

iGIS currently uses .zip files to import and export data.

A zip file  is a compressed folder that saves on space, allowing faster transfers. A zip can be created naturally on modern desktop operating system.  Usually this is done by selecting the items you want to zip, right clicking on them and selecting the option along the lines of “compress” or “send to>compressed (zipped) folder”.


For iGIS to use spatial data, the .dbf, .shp and .shx must not be contained in a subfolder within the zip.
