Thanks, it helps :-)

The following call is guilty:

8 -> ange-ftp-fix-name-for-vms: name="\"/$DISK1!/GRUNWALD/\"" reverse=nil
8 <- ange-ftp-fix-name-for-vms: "[.\".$DISK1!.GRUNWALD]\""

This reminds me, that we have changed the quoting for file names a while
ago. This results in surrounding a file name under Windows by '"', like
"/$DISK1!/GRUNWALD/".  Obviously, ange-ftp-fix-name-for-vms must be
aware of it.

Could you, please, check whether the following patch helps?
