= Installed Directory Layout =

Typically the OSGeo4W tree is installed in C:\OSGeo4W but it is permitted to be located anywhere on the system.  All paths below are relative to the user selected root directory.
 
 * '''/apps''': Directory for applications that need their own directory tree, and don't fit conveniently into /bin, /lib, etc.  Each app appearing here should have a subdirectory with a name closely related to the name of the package. 
 * '''/bin''': most .exe and .dll files intended to be in the user path.  The apache alias '/cgi-bin/' also points to this /bin directory.
 * '''/doc''': LICENSE.txt, README.txt, INSTALL, COPYING and AUTHORS.
 * '''/etc/ini''': .bat files to be called from OSGEO4W_ROOT/osgeo4w.bat - usually these contain SET statements for required environment variables.
 * '''/etc/licenses''': 3rd-Party Packages Licenses Policies. 
 * '''/etc/postinstall''': per package post-install scripts.
 * '''/etc/preremove''': per package pre-removal scripts.
 * '''/etc/setup''': used by cygwin setup to keep track of installed packages. 
 * '''/http.d''': apache configuration files, one per package. See the "Web Application Package Guidelines" section below for more information. 
 * '''/include''': include files required for building additional packages and executables.
 * '''/lib''': static and stub libraries required for building additional packages and executables.
 * '''/share''': static support data files.
