What is an RW2 file?

The RW2 file extension is the successor to the RAW format, used exclusively for raw images produced by Panasonic Lumix digital cameras. It stores unprocessed data from the image sensor along with a unique header containing metadata such as lens information, shutter speed, ISO settings, and color profile tags. The format allows for non-destructive editing by saving parameter adjustments as sidecar files or database entries rather than altering the original pixel data. It typically employs a proprietary lossless compression algorithm.

How to open an RW2 file

RW2 files are supported by professional post-production software including Adobe Photoshop (Camera Raw plugin), Adobe Lightroom, and DxO PhotoLab. Panasonic bundles the SILKYPIX Developer Studio software with their cameras for native decoding. Windows 10 and 11 users can view these files in the Photos app after installing the Raw Image Extension. macOS users can preview and edit RW2 files natively through the Preview app and Photos app, leveraging Apple's system-level raw engine.

What is an ICO file?

The ICO format is an image container specifically designed for Microsoft Windows to store icons for executable files, folders, and applications. Introduced with Windows 1.0, it can encapsulate multiple raster images of varying dimensions and color depths (specifically BMP or PNG frames) within a single file to support dynamic scaling across different display resolutions. The structure comprises an ICONDIR header referencing one or more ICONDIRENTRY directory entries, allowing the operating system to select the appropriate 16x16, 32x32, or 48x48 pixel resource based on the current UI scaling settings.

How to open an ICO file

ICO files are natively supported by the Microsoft Windows operating system, which automatically renders them in the File Explorer and taskbar. On macOS, Apple Preview handles the format natively. For editing or detailed inspection of the contained bitmap layers, raster graphics editors such as GIMP, Adobe Photoshop (via plugin), or Paint.NET are required. Web browsers also natively render ICO files when they are designated as favicons.
