Which operating system can you give smallest file name? A. Ps/2 B. Dos C. Windows D. Windows NT

The correct answer is C. Windows.

Windows allows file names up to 255 characters long, including spaces and special characters. PS/2, DOS, and Windows NT all have shorter file name limits.

• PS/2 allows file names up to 8 characters long.
• DOS allows file names up to 8 characters long, plus a 3-character extension.
• Windows NT allows file names up to 255 characters long, but only the first 127 characters are visible in the file system.

The reason for the different file name limits is that the file system used by each operating system has different limitations. The file system used by Windows is more advanced than the file systems used by PS/2, DOS, and Windows NT, and it can therefore support longer file names.
