Did FAT-16 support comparatively short file names referred to as 6.3 file names?

Yes, FAT-16 supported short file names, commonly referred to as the 8.3 filename convention, which allowed for a maximum of eight characters for the filename and a three-character file extension. This format enabled users to create files with names like "example.txt." However, the naming convention was limited, and additional file systems, like VFAT, were introduced later to support longer and more descriptive filenames.
