- Description
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
- The TN1 file type is associated with the Tiny low-resolution image format, primarily used in the early days of personal computing. It was designed for simplicity and to accommodate the limited storage and processing power of older computer systems. TN1 files typically contain small, often icon-sized, images. Due to advancements in technology and the development of more efficient and versatile image formats, the TN1 format is now considered obsolete and is rarely used.
