Abstract: An envelope form for a computer storage member such as a floppy disk having a number of named computer files recorded thereon is disclosed. It comprises a sheet form configured and dimensioned to be fed into a printer. A directory printing surface portion substantially coincides with the area where a computer normally drives a printer to print a directory listing of the names of the files. Marks are positioned on the sheet form and are configured and dimensioned to define an envelope blank having a front panel and a rear panel. The panels substantially coincide with the directory printing surface portion. An envelope closing extension is associated with and is substantially adjacent to one of the panels. The envelope closing extension is positioned, configured, and dimensioned to be folded over to close an open side of an envelope body formed by the folding of the front panel over the rear panel.
