This vql 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:

Some audio playback programs, such as Winamp still support the VQL format and can work with it.

How to convert:

Possibly can be converted like any other audio format.
