Invalid Filenames
Although you do have some freedom when naming your files,
there are certain names that you may not use, because ms-dos
reserves them for specific devices that your computer uses. These
invalid names are: awe, clocks, com, con, keybdS, Ipt, 1st, mil,
prn, and scrn$. You may use these names as extensions, but
remember not to use them to name your files.
The ms-dos directory Directories
The names of your files are kept in a directory on each disk. The
directory also contains information on the sizes of the files, and
the dates they were created and updated.
If you want to know what files are on your disk, you can use the
dir command. This command tells ms-dos to display all the files in
a specific directory on a disk. For example, if your ms-dos disk is
in drive A and you use the dir command, the directory display
would look similar to this:
: OOp
