I use WinBox for MacOS. Uploading files to the router is choppy and slow. I attached a video which shows the effect (it is zipped because no video content types are allowed).

However, using Webfig upload is quite fast. Unfortunately, Webfig only supports uploading into internal storage which is limited and the file I need to upload is bigger than internal storage available. Therefore I want to upload direct to the folder on the usb drive. This is not supported by Webfig but possible using WinBox.

For me it would be fine to wait for the upload to finish but often the upload does not complete for any reason.

Also I cannot mount the usb-drive on my Mac because I need to use it for containers, means it has to use filesystem ext4 which is not supported by MacOS.

Any idea what reason this could be or any ideas for workarounds?

Thx,
Stephan

Using scp is faster and more reliable:
But also only about 200kB/s.

I saw that also SMB can be activated for USB drives but I didn't manage to get it work.
