      Hi – Anyone out there with a knowledge of the old DOS commands? I have a number of DOS files on my workshop computer (W98) having a file extension .CON which I would like to be able to display in date order. Reference to the manuals indicate that the generic command DIR *.CON can be modified by a /switch attribute which I can get working when using /p (to display one screen at a time) but have not been able to get the /d attribute working in order to display the files in date order. Any suggestions as to where I am going wrong?.

          dir *.con /od

          Edit – if you type any DOS command with the /? switch, it lists all available options e.g. dir /?

            Microsoft changed DIR slightly with every release! This website seems to cover all the variations.

            Try

            DIR *.CON /O:D

            or, to reverse the order

            DIR *.CON /O:-D

            /T controls which datetime is used by the sort if the default isn't what's wanted. TC=create; TA=last read; TW=last write

              Greensands,

              Open up a DOS Shell by typing "cmd" (without the " symbols) in the search window then press enter.. The Dos pop up window will open. Typing "Help " followed by any command name, will display format of the command and the switches which can be used.

              One useful switch that is not listed is the > character followed by a file name. This will divert the screen output into the named file, a very useful feature

              Below is an example from Windows 10, I added the last line to show the piping command:-

              C:Usersgordo>help dir
              Displays a list of files and subdirectories in a directory.

              DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
              [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

              [drive:][path][filename]
              Specifies drive, directory, and/or files to list.

              /A Displays files with specified attributes.
              attributes D Directories R Read-only files
              H Hidden files A Files ready for archiving
              S System files I Not content indexed files
              L Reparse Points O Offline files
              – Prefix meaning not
              /B Uses bare format (no heading information or summary).
              /C Display the thousand separator in file sizes. This is the
              default. Use /-C to disable display of separator.
              /D Same as wide but files are list sorted by column.
              /L Uses lowercase.
              /N New long list format where filenames are on the far right.
              /O List by files in sorted order.
              sortorder N By name (alphabetic) S By size (smallest first)
              E By extension (alphabetic) D By date/time (oldest first)
              G Group directories first – Prefix to reverse order
              /P Pauses after each screenful of information.
              /Q Display the owner of the file.
              /R Display alternate data streams of the file.
              /S Displays files in specified directory and all subdirectories.
              /T Controls which time field displayed or used for sorting
              timefield C Creation
              A Last Access
              W Last Written
              /W Uses wide list format.
              /X This displays the short names generated for non-8dot3 file
              names. The format is that of /N with the short name inserted
              before the long name. If no short name is present, blanks are
              displayed in its place.
              /4 Displays four-digit years

              Switches may be preset in the DIRCMD environment variable. Override
              preset switches by prefixing any switch with – (hyphen)–for example, /-W.

              C:Usersgordo>help dir >help.txt

                  I seem to have a residual bit of fluff in my head which says FAT32 was date orientated and NTSF was alphabetic
