Can't Access USB Floppy Drive within DOS Program

[chrism]

I'm trying to use an old DOS program in VDos that allows me to work on show files from an old theater lighting control console. Basically, I can save the shows from the lighting console onto a floppy disk and load them into this DOS program to edit them or save them to my computer. The floppy itself is formatted under a proprietary format that only the lighting console and the DOS program can read, so I can't open the disk directly in Windows and need the DOS program to read it and convert it.

So here's the problem... I'm using a USB floppy drive connected to my Windows 10 laptop to access these disks. I can access the drive itself with DOS/Windows formatted floppy disks withing VDos, but I can't access the drive withing the DOS program I'm running. I can only access the drive within VDos when it's not running a DOS application, and I can't access the drive from within the application itself. Any ideas how I can access the USB floppy drive within this DOS application on VDos?

BTW... the DOS application I'm using is called ETCEdit and can be downloaded here: www.etcconnect.com/Products/Legacy/Console/Others/MicroVision-FX/Software.aspx

The lighting console I'm using is an ETC MicroVision FX

vDos uses the Windows filesystem. If that can’t access the floppy disk, vDos can neither.

ETCEdit will use low level (INT 13?) disk functions to access data on the floppy, and vDos doesn’t support that.
You can access the floppy at the vDos command prompt, list its contents, but not for instance copy files off it?

You could try DOSBox, that emulates a DOS PC far more to the hardware level.
