What is a RU file?

RU files mostly belong to Browser/Updater.

Your RU file may not be a single standard type. It can be one of several file kinds based on its internal format.
If the file is a firmware update (often used in Netgear devices), it contains update code that a device reads to refresh its software. In this case, the file is used by a dedicated updater tool provided by the device maker.
It can also be a web page snapshot saved in the MHTML format. This type bundles HTML, images, and scripts into one file. You can open it in a browser such as Google Chrome.
Another possibility is that the file is a JPEG image stored as a JFIF file. This is a standard raster image that you can view with any common image viewer. More technical details are available at JPEG.org.

How to know what it is:

Firmware: Look for instructions from your device maker and use the dedicated firmware update tool.
Web Snapshot: If it displays as a complete web page when opened in a browser, it is in MHTML format.
Image: If the file shows a photo or graphic, open it with an image viewer.

FilExt.com tip: Identify the type by checking the file’s content or header with a file analysis tool.

How to open a RU file

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