# Update Kits

An update kit updates applications that are installed on the system. The installation process searches for all the valid applications to update and copies only the programs and data files for applications found. The update kit contains only programs and data files that need to be updated to a higher version, not full applications. An update kit may contain several applications on the media, although only a few may need to be installed. Update kits must contain the file UPDATE.TXT on the root directory of the first volume of media.
