When you use the DIR command with the /O switch at a command prompt,
you may receive the following error message:
The directory listing is then displayed, but it is not sorted as you
There are more files in the directory than the command interpreter
(COMMAND.COM) can sort. The maximum amount of memory that COMMAND.COM can
allocate for a DIR operation is 64 kilobytes minus 512 bytes. Each file
displayed by the DIR command requires 22 bytes for its entry, making the
total number of files that can be displayed in a sorted directory equal to
2295 files [(65536-512)/22].
Microsoft is researching this problem and will post new information here
in the Microsoft Knowledge Base as it becomes available.
The MS-DOS DIR command is internal (built-in) to COMMAND.COM. The DIR
command uses memory allocated by COMMAND.COM for its processing.
For more information about the DIR command and its sorting options, type
dir /? at an MS-DOS command prompt.
