This page is a listing of libraries of user defined functions (UDF). These libraries have been written to allow easy integration into your own scripts and are a very valuable resource for any programmer.
This list is probably not complete (358 UDFs on 2020/09/03), but constantly supplemented. If you do not find a solution here, ask a new question on the forum.

The listed UDFs might have been written for older versions of AutoIt. So there is no guarantee that every UDF works smoothly with newer versions.
None of the UDFs has been tested by the maintainers of this list so you as a user need to make sure that they deliver the expected results.
