A "move" in Explorer is usually a rename operation if it is inside of a single share or device. Usually such a rename operation returns NT_STATUS_NOT_SAME_DEVICE and the client has to move the file by manual copy and delete operations. If the rename by copy is done by the server this can be much more efficient. vfs_crossrename tries to do this server-side cross-device rename operation. There are however limitations that this module currently does not solve: </p><div class="variablelist"><dl><dt></dt><dd></dd><dt></dt><dd></dd><dt></dt><dd></dd><dt></dt><dd></dd></dl></div><p> </p><p>This module is stackable.</p></div><div class="refsect1" title="OPTIONS"><a name="id266849"></a><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">crossrename:sizelimit = BYTES</span></dt><dd><p>server-side cross-device-renames are only done for files if the filesize is not larger than the defined size in MiB to prevent timeouts.
