A replay dropped anywhere on the window, or opened from Explorer (cold
start or into the running app), is added the way Add Replay adds one,
the Replays tab opens, and a single replay opens in the viewer. Several
land on the tab; one that can't be read says why. Leaving the editor goes
through the unsaved-work guard, and staying adds nothing.

The installer and MSIX register .vrf. Ventrilo also uses the extension,
so the installer joins its Open with list and takes the default only
when no other program has it.
