I'm trying to find a way to check if a directory on a NAS contains
any music files. .flac .mp3 .m4a

I've had the realisation this morning that OS_File 13 is case
sensitive so setting R1 to point to */flac will not cut it. So to
find if a (NAS) directory contains any flac files it looks like I
would need to test for flac and Flac and FLAC etc. any combination.

The only solution I can see is to use OS_GBPB to read the name of
file after file and mask out the upper lower case bit ie &DF and if
nothing is found early I have to read every name in the directory.

Is there a better way?

Cheers,

Bob.
