I've spent a bit of time using the DOS plus (2.1) environment and its working great.
Creating directories and copying files across from A: drive to run them from the C: drive on CF (datacentre) HD... All good.
I'm struggling to delete ANY files once created on either A: or C:
ERASE/ERAQ are not working they just flag ' file not erased'... DEL does the same.
Is there a specific command I'm not using?
From memory, in DOS 5.0 there was facility for changing ATTRibutes.
Is that the case with DOS Plus?

Thanks Rob... In that case I'm going to re-image the CF card.
That will probably sort it out.

Hmmmm...
I've re-imaged the CF card in my Rertclinic Master.
DOS boots to 2.1 and ERASE is flagging ' file not erased : (filename) '
So I then booted my VideoNula Master with DOS 2.1 3.5" boot disks and that also comes up with the 'file not erased' report when trying to erase a file.

Starting to get somewhere with this....
It turns out that the ERASE command works with internal PI copro tube connection and not with External tube connection.
