.2CH File

The 2ch file extension is associated with the Super Audio CD, an audio format developed by Sony and Philips as a successor of Audio Compact Discs.

It appears that the Super Audio CD was discontinued in 2007.

This 2ch file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

These files were originally meant only for certain Sony and Philips players.

How to convert:
