Software selection based on available storage space involves determining that a data package (e.g., a software component) is not to be loaded (e.g., not to be installed) onto a storage device (e.g., a disk drive) of a computer (e.g., a target computer). This determination is based on the available storage capacity of the storage device (e.g., free disk space) and on a storage requirement of the optional data package (e.g., disk space required by the proposed software component). In some example embodiments, available storage capacity is determined automatically (e.g., by using an application programming interface).
