What is an RWL file?

RWL files mostly belong to Lightroom by Adobe. RWL is the filename extension of high-resolution photographs captured with Leica digital cameras such as the D-Lux 7. RWL images are stored as uncompressed graphical data captured by the camera's image sensor. The file's structure is based on the TIFF/EP format. However, it has a different signature and its MakerNote tag begins with the word "LEICA". While Leica cameras are not shipped with computer software for importing and editing RWL images, various third-party image processors support this format. Some of these programs are Photos, Photoshop, Capture One, Lightroom, and PhotoDirector. RWL is also the filename extension of text-based ring width data files stored in Tuscon (also called decadal or RWL) format. This second type of RWL format is used by various data computation/visualization technologies (including R programming language). You can edit its contents with any plain text editor.

How do you open RWL files?

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