A version management system is disclosed in which a portable information terminal (an electronic organiser, a lap-top or palm-held computer, a cellular telephone, a radio pager, or a wireless facsimile for example) has software remotely updated. The method includes the steps of i) generating a list of files to be changed, on a master server, ii) comparing the size of those files with the amount of available space on the portable device, and iii) maintaining and updating a record of the available portable device space on the master server whenever the modifying files are synchronised between server and remote client. The advantage is that user-intervention-free software upgrades can be made even in portable devices having limited memory and/or storage capability.
