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.
• /lib: static and stub libraries required for building additional packages and executables.
• /share: static support data files.
• /var: currently used by Cygwin setup.exe
