I'm trying to mount a folder from my NAS in a Docker container so I can store and view documents generated by my web app. I'm using Windows and have been struggling with this for a few days. I managed to map the folder to drive Z: and then set it up to mount to /mnt/shared in my docker-compose file, but when I run 'ls /mnt/shared', it's empty. The NAS has FTP enabled, but I'm not sure what else to check since I'm still new to Docker.

I haven't tried this on Windows, only on Linux, but it sounds like you're on the right track. Make sure you mount the remote share properly and create a volume bind in your docker-compose file. You might want to create a test file, like 'testshare.txt', in that folder to see if it's actually writing to it—it could be a path issue.
Since Docker Desktop runs on a virtual machine, you'll need to check the file paths in your file explorer. Make sure the path starts with a forward slash ('/'). Alternatively, you might want to consider directly mounting the NAS partition using NFS in your Docker container to bypass any issues with the Windows file system overlay.
Instead of mapping a Windows drive to the NAS, try mounting the NAS partition directly as NFS in your Docker container. This will simplify things and should show the data in Z: on your Windows machine. Just keep in mind that if your NAS requires credentials, NFS might complicate this since it typically doesn't handle credentials well.
