FluentFTP: GetListing returns wrong name

FTP OS: OS/400 is the remote operating system.

FTP Server: IBMOS400FTP

Computer OS: Windows 10

FluentFTP Version: 40.0.0

Framework: .NET 6

Hi - we have a problem with an specific FTP Server. When we do an GetListing("remote directory) - the resulting file names contains the directory name - and so an download fails because the directory name is wrong (doubled)

Here the ftp server contains an directory “download” - the GetListing shows correctly all files - but the Name contains the directory name - and the FullName shows the wrong directory because “download” is now 2 times in the path?

@robinrodricks As a first step could you put this on the todo list? With the help of @noxe I think this can be done within a sensible timeframe

Ok. I have got some observations and questions, after doing some research.

Does this work with a FluentFTP version prior to V.40?
It seems to me, that by listing a directory, the output download/B0220831.013 is taken as a filename and appended to the listing path, giving a double downloads. This means that as a “quick” fix you could SetWorkingDirectory to download and then GetListing("", FtpListOption.NoPath). Does this work for you?
I can see in the code that there is no adequate reaction to download/B0220831.013 having download/ prepended to the file name. It looks like you are expected to CWD to the actual directory before doing your GetListing.
