File Types

TouchDesigner can import and export most common media file formats. Files can be loaded into TouchDesigner by:

• Drag-and-Drop: Drag a file directly into TouchDesigner and drop it to automatically create an OP or a component.
• Open With... menu: Right-click on a TouchDesigner supported file in Windows and select Open With...->TouchDesigner 0xx to launch TouchDesigner with the file pre-loaded.
• Load a file using Operators like Movie In TOP, File CHOP, File SOP, Audio Stream CHOP. Files can be loaded from disk or from the web using http://file-url.
• Import a file using the import command within TouchDesigner.
• Start TouchDesigner using the operating system shell command touchdesigner filename.ext, which will start TouchDesigner with your file pre-loaded.

Native TouchDesigner Files

TouchDesigner has three native files types:

• .toe: TouchDesigner Environment files are the default file type for creating projects.
• .tox: TouchDesigner Component files let you save out components. .tox files enable the re-use and portability of component libraries.
• .tog: TouchDesigner Geometry files are exports of other geometry types in a native TouchDesigner format.
