ClientLaunch is launched automatically when it is needed. By clicking special ClientLaunch links, you launch common online files with your locally installed programs. macOS automatically chooses the appropriate program for each file format (i.e., the default program). All you have to do is click an ClientLaunch formatted link, and the file opens. The launched files are downloaded and stored temporarily.
ClientLaunch supports these file formats, among others: rtf, jpg, png, avi, mp4, rdp
