Question
You work as a Network Administrator for uCertify Inc. You want to edit the MSDOS.SYS file, in your computer, from the DOS prompt. You are unable to find the file. What is the most likely cause?
Options
- AIt is a read-only file.
- BIt is a built-in command in the COMMAND .COM file.
- CSomeone has deleted the file.
- DIt is a hidden file.
Explanation
MSDOS.SYS carries the hidden and system file attributes, causing it to be invisible in a standard DOS directory listing without special flags.
Common mistakes.
- A. Read-only status prevents writing to a file but does not hide it from directory listings, so a read-only file would still be visible at the DOS prompt.
- B. MSDOS.SYS is a standalone file on disk, not a built-in command embedded within COMMAND.COM, and this would not explain why the file is unfindable.
- C. Deletion is possible but is not the most likely cause; the file is present by default on DOS/Windows systems and is protected by its system attribute, making accidental deletion uncommon.
