Files can be grouped into different categories. These categories group images of the same function, type and behavior. Many different file types of different files extensions can belong to the same category.
For example the file formats AI (extension .ai) and SVG (extension .svg) both belong to the category of vector image files.
More popular examples for categories include:
- audio
- application
- archive
- executable
- raster image
- text
- video
But there are many more.
