My suggestion would be: a) Make KMountPoint return true for probablySlow for your path (if does not already) b) Make the file ioslave honor KMountPoint::probablySlow for those kind of "expensive" operations (also i think there's a way to tell kio that you want slow operations even if you're in a network) Note i'm not an ultra expert on the field so i may be saying silly stuff :D Cheers, Albert > > I am browsing throught the kio code, however it is very so[phisticated and > therefore complex codebase.
