. html and. TPL

I see some colleagues static pages are all used. All HTML is used. TPL
What difference does it have?

Reply to discussion (solution)

is the template View page estimated? Template file, suffix name does not affect.
If the user is directly accessible, it is not a strange suffix named TPL.

Look at the scene, do you use a frame?

With Smarty.

HTML General static Web page file
TPL is typically used for template files for frameworks, CMS, and template engines.
Smarty is also used as a template file with the TPL suffix

It depends on what you've developed.
