Network folder

[wonder]

The ~/.xsession-errors file is a normal txt log file. You can view it with a simple text editor. It lists all errors reported by graphical applications that aren't shown as an error dialog or even for crashed applications.
I suggest opening that file and having a look if you find samba, samba-mounter or cifs references that might helping resolve this issue.

Ok. But I don't view or localice ~/.xsession-errors file...

As for samba-mounter that is the application name of the application to mount smb network shares linked in the network folder on the desktop. The command itself might be called differently (I don't know it from the top of my head)

Ok, but also, I don't know what command I need execute in terminal for view if have some error (sorry if I not explained well).
If execute in terminal "samba-mounter" appear that I indicate in my last reply.

Thank you!
