Handling verdict
The originating application is the safest default; browser support is not assumed.
Use a format-aware application rather than a plain-text editor.
The registry does not declare compressibility; compare encoded size before enabling it globally.

HTTP response headers
Content-Type: model/vnd.mts
Content-Disposition: attachment; filename="example.mts"
X-Content-Type-Options: nosniffThe MIME type describes the payload, Content-Disposition controls whether the browser previews or saves it, and nosniff prevents the browser from silently substituting a guessed type.
HTML file input
accept=".mts,model/vnd.mts"Use this value on <input type="file"> to steer the picker toward .mts, its known aliases, and files reporting model/vnd.mts. It improves selection, but it is not validation—check the bytes again after upload.

How to work with .mts
operational notesOpen it with the format-aware tool first
Start with Blender, Unity, CAD suites. Maintain consistent scale units and include textures so downstream tools render correctly. If the file came from someone else, keep the original untouched and work on a copy so a failed conversion cannot destroy the only source.
