The utm file extension is associated with the BioWare Aurora game engine, used by Neverwinter Nights and some other games.
A store is an object that exchanges items and gold with the player. A UTM resource defines the items in the store's inventory, its buying and selling markup, and whether it purchases items marked as stolen.
Stores are stored in the game and toolset using BioWare's Generic File Format (GFF).
Open a utm file with the Aurora Toolset supplied with the Windows version of Neverwinter Nights. The toolset can display and edit the store's inventory and trading properties.
A GFF-aware Neverwinter Nights resource editor can also inspect the file.
A utm file is an engine resource rather than a general-purpose document, so it has no useful standalone conversion format.
Use the Aurora Toolset to edit the store and save it as a UTM resource, or include it in the relevant Neverwinter Nights module. A GFF editor may provide data export for inspection, but that does not convert the store into another game format.
