|
|---|
| 3 | server side rename operations even if source and target are on
|
|---|
| 4 | different physical devices. A "move" in Explorer is usually a
|
|---|
| 5 | rename operation if it is inside of a single share or device.
|
|---|
| 6 | Usually such a rename operation returns
|
|---|
| 7 | NT_STATUS_NOT_SAME_DEVICE and the client has to move the file by
|
|---|
| 8 | manual copy and delete operations. If the rename by copy is done by the
|
|---|
| 9 | server this can be much more efficient. vfs_crossrename tries to do
|
|---|
| 10 | this server-side cross-device rename operation. There are however
|
|---|
| 11 | limitations that this module currently does not solve:
