.APLN File

The apln file extension is associated with the Adobe InDesign professional layout program for Mac and Windows computers for print and digital publishing.

The apln file stores plug-in created by Adobe or 3rd party developers that adds new extra features to InDesign.

How to open:

Plugin .apln files are intended to use only with Adobe InDesign. You can import it to InDesign and add new functions to this DTP software.

How to convert:

As far as we know, this .apln file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
