Your problem is not that the files are of an "unknown type. It is that your system cannot find "webdevs". That is what the error message says.
I have no experience with webdavs, but I found this that might help.
Are you usin glinux? is rsync an option for you? There's a lot of info on the web about rsync for remote connections.
[QUOTE=dannybpng;4025244]I am trying to copy some M$ created files from and to a webdavs system. Files with the type: "unknown", will not copy. I get the following error message:
File or folder webdavs: ... does not exist.
