If found and parsed correctly (the TXTH may be rejected if incorrect commands are found) vgmstream will try to play the file as described. Extension must be accepted/added to vgmstream (plugins like foobar2000 only load extensions from a whitelist in formats.c), or one could rename to any supported extension (like .vgmstream), or leave the file extensionless.
You can also use ".(sub).(ext).txth" (if the file is "filename.sub.ext"), to allow mixing slightly different files in the same folder. The "sub" part doesn't need to be an extension, for example:
- 001.1ch.str, 001.1ch.str may use .1ch.txth
- 001.1ch.str, 001.1ch.str may use .1ch.txth
- 003.2ch.str, 003.2ch.str may use .2ch.txth
- etc
