The present invention relates to a means, system and method for controlling the storage space required by a storage means which contains information items associated with an information transfer application. The information transfer application is typically an email application 10 which allows a user to send or receive information items such as electronic mail, electronic documents, electronic files and the like, and stores the items in a mail database or mail file 23 which utilises the storage means. The application 10 includes a transfer control means 20 which is activated whenever a user attempts to access a received item 50 or create a new item 32 for sending. Once activated, the transfer control means 20 compares 35 the storage space required by the storage means to store the items contained in the database 23 with a first set level and prevents further transmission of information items if the required storage space exceeds 37 a first set level. The transfer control means 20 notifies 38, 52 the user when the storage space required exceeds 37 the first set level. The transfer control means 20 may also notify 42 the user when the storage space required exceeds 41 a second set level which is lower than the first set level, to provide the user with warning that the storage space required is approaching the first set level.
