Transferring files between client and host computers
You can exchange files with the host computer.
This section explains the VNC Enterprise Edition file transfer mechanism. You should use this mechanism to exchange files in all circumstances except when the host computer is running Windows and VNC Server is in Service Mode, in which case you can copy and paste files in the standard way for Windows. Follow the appropriate instructions for the platform of the host computer below.
Note: For more information on VNC Server in Service Mode, see Running multiple instances of VNC Server.
If transferring files fails for any reason, start with Troubleshooting file transfer.

Disabling and enabling file transfer
You can disable file transfer while the current connection is in progress.
To do this, open the VNC Viewer
Properties dialog and, on the Inputs
tab, turn off Enable file transfer. For
more information on this dialog, see Using the VNC Viewer Properties
dialog. The Send Files To VNC Server
VNC Viewer toolbar button is disabled.
You can enable file transfer again at any time.
If file transfer does not work, check the following:
1. VNC Viewer may have been configured to disable file transfer. To see how to enable it again, read Disabling and enabling file transfer.
2. VNC Server may have been configured to prevent file transfer. If this is the case and you do not have access to the host computer, you will need to consult your system administrator or a host computer user. If you do have access to the host computer, and sufficient privileges to configure VNC Server, you may be able to allow it again. For more information, see Preventing file transfer.
3. VNC Server may have been configured to prevent you transferring files. If this is the case and you do not have access to the host computer, you will need to consult your system administrator or a host computer user. If you do have access to the host computer, and sufficient privileges to configure VNC Server, you may be able to allow it again. Alternatively, you may be able to connect as a different host computer user and access this functionality. For more information, see Restricting functionality for particular connected users.
4. Under UNIX or Linux, for VNC
Server in Virtual Mode, a program called vncconfig
may not be running. If this is the case, no VNC
Server icon
is displayed in the
Notification Area, and file transfer is disabled. To enable it
again, type vncconfig in a Terminal window,
and press the ENTER key.
Note that under some versions of UNIX, a VNC Server icon is never available. However, file transfer may still be enabled in this case.
