CkFtp PutTree not working with UNC pathes any more

Question

With Chilkat-Library starting version 9.5.0.76 the function PutTree of CkFtp2 did not work with UNC-paths any more. It tries to change the remotedir like the local UNC-path.

Code sample:

CkFtp2 ftp;
ftp.put_Hostname("ftp.example.com");
ftp.put_Username("test");
ftp.put_Password("test");

bool success = ftp.Connect();
success = ftp.ChangeRemoteDir("/");
success = ftp.PutTree("\\\\server\\daten\\Ent\\Seb\\Versionssystem");
success = ftp.Disconnect();

Until version 9.5.0.75 this code works fine. Is this a bug or did I am missing a new flag/option to set the behaviour to the old one?

I ran into this same error on 9.5.0.82. It turned out that the change to root ftp.ChangeRemoteDir("/") was the culprit. The account we had did not have permissions to root.

The ChangeRemoteDir command didn't error but every request after produced the "Can't change directory to... No such file or directory" error.

The ftp.PutTree command worked after skipping the change to root.
