The filing model is based on the.paper office but is even simpler; documents are placed in files which are on disk( ette)s ('drawers' in the paper office). As detailed in .chapter 2, many of the rest.rictions that exist in the paper off ice have been lifted; those that still remain are identical to those that exist in the paper officet e.g. disks (drawers) have a finite storage capacity. The user interacts with the Filer via .the dialog box - window$ are reserved for use by documents on the desktop.. This makes it easy for the user to get to the Filer by selecting a single menu option rather than hav1ng to search through the documents on the desktop. In general, the user specif1es the (set of) document(s) s/he wants to operate on.and then the operation, just as in the rest of Lisa. The Filer steps the. user through the standard document page 1 July 23, 1981 A1'PLE qoNFIDENTIAL Project ldentificatioll specification procedure (which the user can easily override) prompting for informacion and providinghi.Dl/her with tbe v11lU choices..
