What is a RAW file?

The RAW file extension refers to a minimally processed image file format used primarily by older Panasonic and Leica digital cameras, or as a generic descriptor for binary raw data streams. In the context of photography, these files contain the direct readout from the CCD or CMOS image sensor, preserved at high bit depths (typically 12-bit or 14-bit) without lossy compression or in-camera processing like sharpening or white balance application. This 'digital negative' format retains the maximum dynamic range captured by the hardware.

How to open a RAW file

Opening RAW files necessitates image processing software equipped with the specific demosaicing algorithms for the camera model used. Adobe Photoshop (via Camera Raw), Adobe Lightroom, and Corel PaintShop Pro are standard professional tools. For open-source alternatives, Darktable and UFRaw utilize the libraw library to decode these files. Native OS support on Windows and macOS is generally robust for recognized camera models, provided the OS is updated with the latest raw compatibility drivers.

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.
