MS-DOS

= SUMMARY =

Microsoft Word for DOS does not allow you to save a document with the same name as a valid DOS device. If you attempt this, Word begins to save the document, beeps, and then may display one of the following messages:

Cannot write to a read-only file

Document disk full

File is not available

Word disk full

The following MS-DOS device names should not be used:

AUX, CON, COM1, COM2, COM3, LPT1, LPT2, LPT3, NUL, and PRN

Word version 5.5 also does not allow you to save a file with the additional device names:

LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, COM4, COM5, COM6, COM7, COM8, COM9

Word 5.5 displays the message “The document disk is full or the file is read-only” if you specify one of these device names when using the Save As command from the File menu.
