ONE

Microsoft OneNote File Format

The ONE file format, also known as OneNote Document, it was developed by Microsoft for storing digital notes, including text, images, audio, and other multimedia content, primarily used in Microsoft OneNote. It is supported by Microsoft OneNote across platforms, including Windows, macOS, iOS, and Android, and can be accessed via web-based OneNote or third-party tools with limited compatibility. The format organizes notes into hierarchical sections and pages, supports advanced features like embedded files, handwriting recognition, and cloud synchronization, making it ideal for collaborative and multi-device workflows.

ICO

Microsoft Icon File

The ICO (Icon File) format is a widely used image file format primarily designed for storing computer icons in Microsoft Windows operating systems. It is supported by various graphic editing tools like Adobe Photoshop, GIMP, and online converters, as well as being natively compatible with Windows for displaying application and system icons. The format can store multiple images of varying sizes and color depths (up to 32-bit RGBA) within a single file, allowing for high-quality, scalable icons with transparency and anti-aliasing support.
