Microsoft Windows Cursor
The standard format for static mouse cursors on Microsoft Windows.
The CUR format is the standard file format for static mouse cursors in the Microsoft Windows operating system. It is structurally almost identical to the ICO (Icon) format, with one key difference: the header contains a defined 'hotspot'. The hotspot specifies the exact pixel coordinate (x, y) that registers the click, such as the tip of an arrow pointer.
A CUR file starts with a header similar to an ICO file, but the 'image type' field is set to 2 (Cursor) instead of 1 (Icon). For each image in the file (it can contain multiple sizes/depths), the directory entry stores the hotspot X and Y coordinates instead of the color planes/bpp fields found in ICOs. The image data itself is typically a BMP with a 1-bit AND mask for transparency, or a PNG in modern versions.
Introduced with Windows 1.0, the format has evolved alongside Windows. Originally supporting only monochrome, it grew to support 16 colors, 256 colors, and finally 32-bit alpha-blended cursors in Windows XP.
Bitmap Image File
The classic uncompressed Windows image format.
BMP (Bitmap) is a raster graphics image file format used to store bitmap digital images, independently of the display device. It is one of the oldest image formats still in use, historically associated with the Microsoft Windows operating system.
BMP files typically store color data for each pixel in the image without any compression. This results in very large file sizes but perfect quality and extremely fast decoding. While it supports RLE compression, it is rarely used.
Introduced with Windows 3.0 in 1990. It was the standard format for Windows wallpapers and system graphics for decades.
