Is MS-DOS case sensitive?

Question:

Is MS-DOS case sensitive?

Answer:

Overall, MS-DOS is not case sensitive. Unlike case sensitive command line operating systems, such as Linux, commands such as the MS-DOS dir command can be typed as "DIR", "Dir", or "dir" and still be able to run. In case sensitive operating systems, only the lowercase command would work.

However, there are some commands that have additional options or switches that are case sensitive. If these options or switches are case sensitive, it will be mentioned on the Computer Hope MS-DOS commands page.
