Filezilla hangs when used with Mountain Duck

Hi, I am a Filezilla user, and would rather not switch away. However as I am now working from home, I needed a faster way to connect to our work WebDAV server through Finder. I found MountainDuck to be very helpful in this regard (as the native Finder WebDAV connection is excruciatingly slow). However if I use a 'local' folder with a MountainDuck location (which usually appears outside Finder as a cached folder like '~/Library/Group Containers/ Support/duck/Volumes/...').

FileZilla appears to hang when you attempt such a connection with a MountainDuck 'local' folder. The remote and 'local' folders do eventually resolve, but it can take several minutes, and most users would interpret this as a crash and just abandon the process. For comparison Finder and Transmit (the FTP programme) both have no issues connecting to the folder near instantaneously.

I have also tried this on Windows and have a similar experience. I appreciate this is perhaps an unusual combination of applications, but since it caused me to (temporarily at least) abandon FileZilla, I thought you should know so you could fix the issue.

This is the expected behavior if remote resources are treated like local resources, especially if they for some reason are not available.

Unfortunately the POSIX API does not contain a way to query whether a given path is a local resource. For best results never mount remote resources into the local filesystem hierarchy, always use specialized programs to access remote content.

Thanks for the response. Yes I appreciate it's not the usual approach, however the speed of the connection I now have using MountainDuck means for most purposes I can work as if I am back in the office with the work server on the local network, so I wouldn't want to lose that. So far FileZilla is the only application which I have used that has difficulty loading these folders at speed.
