Custom Client Download Repositories
You may configure the URLs to your own download repositories for your ownCloud desktop clients and mobile apps in config/config.php. This example shows the default download locations:
OWNCLOUD_CUSTOMCLIENT_DESKTOP='https://owncloud.com/desktop-app/'
OWNCLOUD_CUSTOMCLIENT_ANDROID='https://play.google.com/store/apps/details?id=com.owncloud.android'
OWNCLOUD_CUSTOMCLIENT_IOS='https://itunes.apple.com/us/app/owncloud/id543672169?mt=8'
Simply replace the URLs with the links to your own preferred download repos.
