I'm running SnapPea to connect my android phone.
It is using SwiFTP as an ftp server to expose the Android file system.

When browsing with Windows Explorer it all works as expected,
But with WinSCP I can't CD into any directory (see log below).
I've noticed two forum topics on this issue from 2012 that seem to not have been resolved.

WinSCP gets confused by absence of leading slash in response to PWD command.

Can you test what is a response like when you are two folders deep?

OK, thanks.
WinSCP definitely cannot copy with this.
To me it looks at least like an inconsistency, if not a bug, when root has path /, but when entering subdirectory, a leading slash disappears.
