Just like Internet Explorer you can also use these GIS browsers to search for files. Once you have found the file you are looking for, unlike Internet Explorer, you can preview it. These map files could be either vector, raster or database format. Besides a preview of your map layer you could also look at the attribute data which is connected to any vector layer. As previously mentioned, you can also look at any metadata which has been provided. Of course, none of this functionality is available within Internet Explorer, which is your standard method for managing files within the Windows operating system. These limitations within Internet Explorer explains why ArcGIS, MapInfo and QGIS now offer these specialist browser capabilities.
