You're here because you have a file that has a file extension ending in .a5l. Files with the file extension .a5l can only be launched by certain applications. It's possible that .a5l files are data files rather than documents or media, which means they're not meant to be viewed at all.

Controls integrated by a user into an Authorware 5 application output file are stored in files with the .a5l extension, among other pieces of data such as icons and images. An Authorware 5 application output file is an application development project created by an Authorware 5 user, and these are media-rich applications used for e-learning purposes. The Authorware 5 application is software that promotes the development of applications offering media-rich content used in e-learning environments. These applications can be distributed and packaged as online or offline e-learning tools and digital materials. The Authorware 5 application locates the associated A5L data file and references the content stored in the file whenever a user accesses the content of an application project developed using Authorware 5, and the retrieval of these stored elements and objects is also done by the Authorware 5 software when required. Users of Microsoft Windows-based systems can use version 5 or later of Authorware to implement support for these A5L files, and version 7 of the Authorware application is widely used by a lot of Microsoft Windows users. Mac users can also use the Authorware 7 software to create these application development projects and integrate into their systems support for files in the .a5l extension.

Launch a .a5l file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .a5l file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .a5l files aren't yet associated with it. In this case, when you try to open a .a5l file, you can tell Windows which application is the correct one for that file. From then on, opening a  .a5l file will open the correct application.

Be careful not to rename the extension on .a5l files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .a5l. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
