What Are AU3 Files?
are Developer Files
primarily associated with AutoIt Ver. 3 Script (HiddenSoft)
(Other files may also be using the AU3 file extension. If you know of any other software using the AU3 file extension, please contact us so that we can update our information accordingly.)
Opening AU3 Files
The easiest way to open a AU3 file
is by double-clicking on it, which will let the computer decide the best way to open it according to the Windows AU3 file association settings.
If your computer opens your AU3 file, but it's the incorrect application, you'll need to change your Windows registry file association settings. In other words, Windows is associating AU3 file extensions with the wrong software program.
Incorrect AU3 file association errors can be a symptom of other underlying issues within your Windows operating system. These invalid entries can also produce associated symptoms such as slow Windows startups, computer freezes, and other PC performance issues.
Therefore, it highly recommended that you download WinThruster
and scan your Windows registry for invalid file associations and other issues related to a fragmented registry.
If the AU3 file
fails to open, it is highly likely that your system lacks the application needed to open AU3 files. It is common for several applications to share the same AU3 file extension label, so it could take some trial and error to figure out what application actually opens your file (if any).
Thus, I highly recommend that you contact the source of your file for more details on what program you need to open your AU3 file. This will save you a lot of time and headaches!
Remember to always take caution when opening files that come from unfamiliar sources or emails.

Is Your PC Healthy?
I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster (Download)
or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.
Happy Computing! :)
