What is an ALP File?

How to Open, Edit, & Convert ALP Files

A file with the ALP file extension is an AnyLogic Project file used with AnyLogic simulation software.

ALP files use the XML format to save everything that pertains to the project, including things like models, the design canvas, resource references, etc.

Ableton Live Pack files also utilize the ALP file extension in Ableton's Live software for storing audio data. You might see those with other Ableton file types, like the Ableton Live Set (.ALS) format.

Another format that utilizes this extension is the Alphacam Laser Post file type. These ALP files are used for storing woodworking components in the Alphacam CAD/CAM software.

How To Open an ALP File

The AnyLogic software, including the free AnyLogic PLE (Personal Edition) version, opens ALP files that it uses as project files. The software works on Windows, Mac, and Linux operating systems.

Like other XML-based files, ALP files can also be viewed in a text editor like Notepad++. Opening an ALP file in a text-only application gives you a behind-the-scenes look at how the file works, but it's really of no use for most people. AnyLogic should be used to open the file in pretty much all cases.

ALP files that are Ableton Live Pack files can be opened with Ableton's Live through the File > Install Pack... menu option. In Windows, the ALP file is unpacked and installed to the user's Documents folder under \Ableton\Factory Packs\, by default.

You can check/change your folder in Options > Preferences... > Library > Installation Folder for Packs.

Note: The Ableton software itself isn't free, but there is a 30-day trial you can install. Free Packs can be downloaded here, at the Ableton website.

Alphacam software opens Alphacam Laser Post files.

Tip: Notepad++ or another text editor can also be used if you're not sure what should open the ALP file. Software not listed above may use the extension as well, in which case opening it in a text editor may help you find some text that indicates what software the file belongs to.

If you find that an application on your PC does try to open the ALP file but it's the wrong application or if you would rather have another installed program open ALP files, see my How To Change the Default for a Specific File Extension guide for help making that change.

How To Convert an ALP File

Some versions of AnyLogic can export a project to a Java application. You can go here to compare the different AnyLogic versions to see which ones support it.

The only free way I know of to convert an Ableton audio file used with the Live software is to open the ALP file in the demo version of Live. Once the audio is fully loaded into the program, use the File > Export Audio/Video... option and select either the .WAV or .AIF file type. If you want to save the ALP file to MP3 or a different format, use one of these free audio converters on the WAV or AIF file.

ALP files used with the Alphacam software may be able to be converted into a new format by using the Alphacam software.

Usually, if this is supported, the application will have the option available in its File > Save as menu or some sort of Export option.
