Questions & Answers
SHZ files: Frequently Asked Questions
What are SHZ files?
SHZ is an ordinary ZIP archive that contains the files of a single Shapefile layer, given the short extension .shz instead of .zip. Inside are the .shp file with the geometry, the .shx file with the index of the shapes, the .dbf file with the table of attributes, and the usual side-car files, such as .prj with the coordinate system and .cpg with the encoding of the text. A layer holds only one type of geometry, which is points, lines, or polygons. A file with several layers is usually named .shp.zip, so the extension tells a program how many layers to expect. The archive is compressed with the standard ZIP method, so a .shz file can be renamed to .zip and opened with any archive tool, and the files taken out. Programs that edit a file inside the archive create temporary files while they work. The older limits of the Shapefile format still apply: the .shp and .dbf files should stay under 2 GB, field names are limited to ten characters, and a layer cannot mix geometry types. The extension is not recognized everywhere, and some services, such as ArcGIS Online, expect a plain .zip with the files in the root of the archive. Supported by QGIS and FME.
