What is a NML file?
The .NML file extension usually identifies a Traktor Collection File. Native Instruments uses this format for their Traktor DJ software. The file stores playlist structures, audio markers, and track data. The software formats this information using the standard XML structure.
A .NML file can also represent an apparel pattern design file used by CODE-MODEL Professional, an exported level file for the NSMBe game editor, or a NewGRF Meta Language file.
How to open NML files?
Because the .NML extension has multiple possible meanings, we recommend using viewer.online/nml to identify the actual format of your file. The viewer.online/nml platform analyzes .NML files to identify their exact format and creator software. It shows which programs can open the file, and usually previews it.
If your file is a Traktor Collection File, you can open it directly in Traktor Pro. Because the file uses text formatting, you can also view the code using text editors like Notepad++.
Best practices and troubleshooting
Always back up your .NML files before editing them manually. A small syntax error in the code can corrupt your entire Traktor music collection. If a file fails to load, check the code using an XML validator.
Summary
Because .NML files use the known XML format, viewer.online/nml can safely open and display them online, eliminating compatibility problems.
