Re: Bug in FTP protocol prevents changing directory
Can you email me a complete log file, showing both entering regular subfolder and symlink?
After experimenting with different FTP servers I figured out it was not a problem with symlinks at all. Log above shows that after getting "/mnt/sdcard" as current directory, WinSCP tries to change directory to "/mnt/sdcard/mnt/sdcard" which of course doesn't exist. Same happens when it tries to enter regular directories (see new log, /system is a regular directory). That's probably something specific to SwiFTP server, because other FTP servers for Android work fine with WinSCP (apart from that one in my other bug report), but still all other FTP clients work perfectly with SwiFTP server.
Anyway, while I was making a full log as requested, after few directory changes WinSCP interface became unresponsive. I waited few minutes before closing window, no new entries were written to log file.

Bug in FTP protocol prevents changing directory
WinSCP in FTP mode fails to enter symlinked directories on some FTP servers. I am using SwiFTP on my android device and all FTP software except WinSCP works well with it. I made a debug log which clearly shows a bug in change directory code:
I attached full log file as well.
