What is it?
CUR is the Microsoft Windows file format used to store static (non-animated) mouse cursors. It is almost identical to the Windows ICO icon format, sharing the same directory-based container structure for holding one or more images.
The key difference from ICO is in the header: CUR files begin with the bytes 00 00 02 00 and each directory entry records a hotspot, the x,y pixel offset that defines exactly where the cursor points. A single CUR file can hold multiple images at different sizes and color depths, letting Windows pick the most suitable one for the display settings; image data may be stored as BMP-style pixel arrays or, in later Windows versions, as embedded PNG data.
Technical Specifications
Pros & Cons
Advantages
CUR is the native static cursor format, recognized directly by the Windows operating system and pointer settings.
Like ICO, a single CUR file can bundle several image sizes and color depths so the system can choose the best match.
The header's hotspot field precisely specifies where on the cursor image the pointer actually clicks.
Support for embedded PNG data allows smoothly anti-aliased, alpha-blended cursors on Windows Vista and later.
Disadvantages
CUR cannot store animation; animated Windows cursors use the separate ANI format.
The format is tied to the Windows pointer system and is not a general-purpose interchange image format.
Legacy BMP-style cursor images are uncompressed, which is acceptable only because cursors are very small.
When to Use It
CUR exists specifically to define how the mouse pointer looks in Windows.

How to open a CUR file
Software for working with CUR files can be categorized into professional tools, free/open-source applications, browser-based solutions, and built-in utilities. Professional tools are suited for designers and developers needing advanced features, while free/open-source options appeal to hobbyists and those on a budget. Browser-based tools offer convenience and accessibility, while built-in utilities provide basic functionality without additional installations.
When selecting software for CUR files, key decision factors include feature fidelity, whether the focus is on editing or viewing, cost models, and platform compatibility. Users should consider export needs, especially if converting CUR files to other formats is necessary. For those who require extensive editing capabilities, a professional tool may be preferable, while simpler tasks may be adequately handled by free or built-in options.
