Nice that you like it! I forgot to mention that gzipped files are supported also! (but not for shapefiles as they are not a single file) This is all possible due to GDAL/OGR /vsizip/ and /vsigzip/ mechanism , more info at http://trac.osgeo.org/gdal/wiki/UserDocs/ReadInZip QuaZIP and zlib are used to get zip file listing (this is optional at compilation, but supported by osgeo4w and linux builds). > > just noticed one thing, if the zip file contains >1 raster then is not > shown in the browser, while if it contains just one it works ok (also > from the add raster dialog). You have to change the "Scan zip" settings (in the general options), the possible values are - No - Passthru - this just sets the uri to /vsizip/file.zip (which is the way gdal/ogr supports zip files) and does not support multiple files - Basic Scan - this opens the zip file and presents the files which extension is supported (.tif, .shp, etc) - Full Scan - this presents the files inside the zip which are valid (takes longer) Default value is Passthru, but perhaps "Basic Scan" would be a better default? I had chosen Passthru as a default before using QuaZip, but it is probably not the best default now.
