QFtp: entering deep folder (cd)

[Raccoon29]

Hi,
qt ftp example does

ftp->cd("qt");

ftp->cd("qt");

To copy to clipboard, switch view to plain text mode 

to change the working directory.
The question is: how to change to deeper folders?

Assume that the server tree is /folder/inner/deeper and from "folder" I have to change to "deeper", how to achieve it?

(I tried

ftp->cd("inner/deeper");

ftp->cd("inner/deeper");

To copy to clipboard, switch view to plain text mode 

ftp->cd("inner");
ftp->cd("deeper");

ftp->cd("inner");
ftp->cd("deeper");

To copy to clipboard, switch view to plain text mode 

but the first says that the folder doesn't exist, while the second says that "deeper" doesn't exists...)

Thank you for your attention
