| 7 | <p><ph conkeyref="vbox-conkeyref-phrases/product-name"/> enables you to drag and drop content from the host to the
|
|---|
| 8 | guest, and vice versa. For this to work the latest version of the Guest Additions must be installed on the guest. </p>
|
|---|
| 9 | <p>Drag and drop transparently allows copying or opening files, directories, and even certain clipboard formats from
|
|---|
| 10 | one end to the other. For example, from the host to the guest or from the guest to the host. You then can perform
|
|---|
| 11 | drag and drop operations between the host and a VM, as it would be a native drag and drop operation on the host
|
|---|
| 12 | OS. </p>
|
|---|
| 13 | <p>At the moment drag and drop is implemented for Windows-based and X-Windows-based systems, both on the host and
|
|---|
| 14 | guest side. As X-Windows supports many different drag and drop protocols only the most common one, XDND, is
|
|---|
| 15 | supported for now. Applications using other protocols, such as Motif or OffiX, will not be recognized by <ph
|
|---|
| 16 | conkeyref="vbox-conkeyref-phrases/product-name"/>. </p>
|
|---|
| 17 | <p>In the context of using drag and drop, the origin of the data is called the <i>source</i>. That is, where the
|
|---|
| 18 | actual data comes from and is specified. The <i>destination</i> specifies where the data from the source should go
|
|---|
| 19 | to. Transferring data from the source to the destination can be done in various ways, such as copying, moving, or
|
|---|
| 20 | linking. </p>
|
|---|
| 21 | <note>
|
|---|
| 22 | <p>At the moment only copying of data is supported. Moving or linking is not yet implemented. </p>
|
|---|
| 23 | </note>
|
|---|
| 24 | <p>When transferring data from the host to the guest OS, the host in this case is the source, whereas the guest OS
|
|---|
| 25 | is the destination. However, when transferring data from the guest OS to the host, the guest OS this time became
|
|---|
| 26 | the source and the host is the destination. </p>
|
|---|
| 27 | <p>For security reasons drag and drop can be configured at runtime on a per-VM basis either using the <b
|
|---|
| 28 | outputclass="bold">Drag and Drop</b> menu item in the <b outputclass="bold">Devices</b> menu of the virtual
|
|---|
| 29 | machine, or the <userinput>VBoxManage</userinput> command. </p>
|
|---|
| 30 | <p>On Windows hosts, dragging content between UAC-elevated (User Account Control) programs and non UAC-elevated programs isn't allowed. For example, if you start <ph conkeyref="vbox-conkeyref-phrases/product-name"/> with Administrator privileges then dragging to or from Windows Explorer, which runs with regular user privileges by default, is not possible.</p>
|
|---|
| 31 | <p>The following drag and drop modes are available: </p>
|
|---|
| 32 | <ul>
|
|---|
| 33 | <li>
|
|---|
| 34 | <p><b outputclass="bold">Disabled.</b> Disables the drag
|
|---|
| 35 | and drop feature entirely. This is the default when creating a
|
|---|
| 36 | new VM.
|
|---|
| 37 | </p>
|
|---|
| 38 | </li>
|
|---|
| 39 | <li>
|
|---|
| 40 | <p><b outputclass="bold">Host To Guest.</b> Enables drag
|
|---|
| 41 | and drop operations from the host to the guest only.
|
|---|
| 42 | </p>
|
|---|
| 43 | </li>
|
|---|
| 44 | <li>
|
|---|
| 45 | <p><b outputclass="bold">Guest To Host.</b> Enables drag
|
|---|
| 46 | and drop operations from the guest to the host only.
|
|---|
| 47 | </p>
|
|---|
| 48 | </li>
|
|---|
| 49 | <li>
|
|---|
| 50 | <p><b outputclass="bold">Bidirectional.</b> Enables drag
|
|---|
| 51 | and drop operations in both directions: from the host to the
|
|---|
| 52 | guest, and from the guest to the host.
|
|---|
| 53 | </p>
|
|---|
| 54 | </li>
|
|---|
| 55 | </ul>
|
|---|
| 56 | <note>
|
|---|
| 57 | <p>Drag and drop support depends on the frontend being used. At the moment, only the <ph
|
|---|
| 58 | conkeyref="vbox-conkeyref-phrases/vbox-mgr"/> frontend provides this functionality. </p>
|
|---|
| 59 | </note>
|
|---|
| 60 | <p>To use the <userinput>VBoxManage</userinput> command to control the current drag and drop mode, see <xref
|
|---|
| 61 | href="vboxmanage.dita#vboxmanage"/>. The <userinput>modifyvm</userinput> and <userinput>controlvm</userinput>
|
|---|
| 62 | commands enable setting of a VM's current drag and drop mode from the command line. </p>
