Notes about the M4A file extension:

Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The M4A file type is primarily associated with 'MPEG-4 Audio Layer'. Files in .M4A format are actually the audio layer of (non-video) MPEG 4 movies. M4A is slated to become the new standard for audio file compression. This format is also known as Apple Lossless, Apple Lossless Encoder, or ALE. It is a new codec designed to provide lossless encoding in less storage space.

Cannot access M4A files on windows?

When windows gives you an error message saying that it
"Cannot open M4A files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

RECOMMENDED:

In both cases it is strongly recommended that you
run a free scan for registry errors.
