...() behind the scenes instead of * the _open() function. This allows much greater flexibility when it comes * to Windows files. It also allows you to open directories, which File.open * cannot do on Windows. * * The access mode defaults to READ_DATA | WRITE_DATA * The share mode defaults to SHARE_READ | SHARE_WRITE * The creation mode defaults to OPEN_EXISTING * The flags default to NORMAL * * To open a directory, pass File::BACKUP_SEMANTICS as the ''flags'' argument. So, with this I can do: dir = "C:\\TEST" # directory fh = File.nopen(dir,nil,nil,nil,File::BACKU...

...t backup semantics only allow you to bypass _security_ restrictions, not sharing restrictions (as well as allowing access to security information about the file). I can't believe it. This means that most backups under Windows are completely useless unless programs avoid opening a file without SHARE_READ. One backup program claims to be able to back up unshared, open files. They say that they do it with a custom kernel driver which allows them direct access to the file. This, of course, is beyond the scope of my charter for modifying rsync. -- Jason M.
