The File sharing portlet includes the following tokens in the PortalServer-DataDir/portals/portal-ID/portletapps/Filesharing/tokens.properties file:
Specifies the type of file repository. By default, only file system is supported, and so the default value is FileSystem.
Specifies the absolute directory for the file repository. By default, this is set to /export/filesharing/repository.
Specifies the absolute directory for file upload staging. By default, this is set to /export/filesharing/temp.
