I have tested several version of WebDAV file lock-unlock function together with FileRun WebDAV connection. In both free and enterprise version of FileRun web UI the lock icon shows up when I lock a file in WinSCP, but no lock icon shown up in the Rights column in WinSCP. The lock icon disappears in the FileRun web UI when I unlock the files in WinSCP, so the lock function seems to work correctly. There is no graphical feedback in WinSCP if a file is locked.
Is it a bug or just a behavior with just the FileRun WebDAV connection?
