What is an OT file

OT files mostly belong to Microsoft Office Lens. OT files are not a single standard format. Their use depends on the software that created them.
  • Extraction Template: In some cases, OT files are used by Microsoft Office Lens as an ontology template. This format works with language understanding software such as LUIS. See more details at Microsoft Office Lens.
  • 3D Mapping: Other OT files serve as an OcTree structure for 3D occupancy grid maps. These files are created by Octomap and are used in robotics and computer vision to represent 3D spaces. More information is available at Octomap.
  • Simulation Trace: A third variant stores simulation trace data from OPNET. These files capture network simulation results and can be analyzed with dedicated OPNET tools. Further details can be found at Riverbed.
    • FilExt.com tip: Each OT file must be opened with its specific application because the content and structure depend on its original use. If you have an OT file, check its header or documentation to confirm which software created it.

    How to open OT files

    You need a suitable software like Microsoft Office Lens to open an OT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OT file directly in the browser:. Just drag the file onto this browser window and drop it.
