What is a NUM file?

NUM files mostly belong to Text Editor. Many NUM files are used to store numeric data. They hold numbers or measurement values that a specific program writes for analysis or record keeping.
Use Cases:
  • Numeric Data File: Contains simple numeric values in text or binary form. This is the standard function for most NUM files.
  • JPEG Image with EXIF: Some NUM files use the JPG format to store image data with embedded EXIF metadata. These files are linked with Samsung Kies; see the Samsung website for more details.
  • Viewing:
    If the file is plain numeric data, open it with a text editor or spreadsheet program. If it is an image file, try using an image viewer or editor.
    FilExt.com note: Check the file header with a hex editor if initial attempts to open the file are unsuccessful, as the structure may vary by application.

    How do you open NUM files?

    You need a suitable software like Text Editor to open a NUM 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 NUM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NUM file directly in the browser:. Just drag the file onto this browser window and drop it.
