DOT at a glance
DOT

For modern Word template workflows, DOTX or DOTM are usually preferable.

ASF
Convert to ASF when you need compatibility with older Windows Media infrastructures, enterprise archives, or inherited streaming libraries that still rely on Microsoft's classic container family.
It is useful for preservation and controlled legacy playback.
For current browser and consumer delivery, MP4 or WebM are generally better choices.
