What is an RW2 file

RW2 files mostly belong to PHOTOfunSTUDIO by Panasonic. RW2 is the filename extension of a proprietary RAW image format developed by Panasonic and used on Panasonic Lumix and Leica digital cameras. Photographs captured by these cameras and saved in RW2 format are made up of minimally compressed pixels captured by the camera's image or motion picture sensor. For this reason, RW2 files are saved in the highest possible picture quality and the files are usually large. PHOTOfunSTUDIO is the program developed by Panasonic for the purpose of importing and editing RW2 images. Third-party programs such as Photos, PaintShop, and XnView also support RW2 format.

How do you open RW2 files?

You need a suitable software like PHOTOfunSTUDIO to open an RW2 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.

RW2 format details:

To view or edit RW2 files you need to know the file format, because it determines how the data in this file is stored. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Knowledge is power - this also applies when dealing with unknown or faulty files.
