Files with .motn extension are motion files from Apple Motion program, part of Apple Final Cut Pro. You can work with these files using Apple Motion program. Apple Final Cut can export .motn files to other formats.
If the .motn file was sent by someone else, ask them to resend it. The file may have errors which prevent accessing it. The inability to open the file does not necessarily mean you lack proper software. Possible problems include file corruption, incorrect registry entries, accidental registry deletion, or incomplete installation of the application supporting the format.
Windows examines the filename extension when you double-click to open a file. If it recognizes the extension, it opens the file in the associated program. When it does not recognize the extension, you must select an app to open the .motn file. It means the operating system lacks a default program for that file type.
Most .motn files are incompatible so you likely need a different application to handle each one. Apple developed the format and Final Cut Pro program. The .motn file was probably created in Final Cut Pro. Tools to work with .motn files include file openers, converters, viewers and editors.
