ani file icon: ani filetype icon

File extension ani is traditionally and mostly used for animated mouse cursors in Windows operating system environment.

The ani file is a structured format (Microsoft RIFF) that contains information about the animation (author & title, steps, length & order of each step...) followed by several frames stored in the icon format.

Each frame/step in an animated cursor is displayed during a short time (delay or length): this is the frame timing. This time is measured in jiffies; 1 jiffy=1/60th of a second~16,66ms.

If your ani files are correctly associated, you can preview them using Windows Explorer: just hit an animated cursor file and select the File Properties shell menu command. Windows will then display the animated cursor on the Properties tab.
