The ICO file extension, standing for "Icon", is integral to Microsoft Windows for storing icons of different sizes and color depths. Its primary use is to display graphical representations of executable programs, files, and folders within the Windows operating system. The ICO format's origins trace back to the early versions of Windows, evolving over the decades to support enhanced resolutions and alpha transparency. Today, ICO files ensure visually consistent and scalable icons that maintain their appearance across various display settings, aligning with modern user interface standards.
The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
