# Directory Structure

The following table describes the directories created during the Filter SDK installation. The variable `install` is the path name of the Filter installation directory (for example,
`/usr/autonomy/KeyviewFilterSDK` on UNIX, or `C:\Program Files\Autonomy\KeyviewFilterSDK` on Windows).

The variable `OS` is the operating system for which the SDK is installed. For example, the `bin` directory on a standard 32-bit Windows installation would be located at `C:\Program Files\Autonomy\KeyviewFilterSDK\WINDOWS\bin`.
