What is an RW file

RW files mostly belong to WinRAR. A RW file is not a single standard type; its purpose depends on the internal format used by its creator.
For example:
  • RAR archive volume – The file acts as part of a compressed archive. Use an archiver such as WinRAR to open it.
  • Raw image file – The RW file may follow the RIFF structure to hold image data. This format is used by image processing tools like RawTherapee and relates to compressed image formats such as WebP (managed by LibWebP).
  • XML report file – In some cases, the file is structured in XML and contains report data generated with Genesis Education Report Writer. You can view it with any XML viewer. More information is available at Genesis Education.
  • ACPI table dump – Other RW files store system-level data such as ACPI table dumps, produced by utilities like RWEverything. Visit RWEverything for details.
  • FilExt.com tip: Because the file extension itself does not define a single use, determining the internal format is key. Open the file with a text editor or a hex editor to inspect its header and then choose the appropriate application.

    How do you open RW files?

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