Transfering files between client and host computers

If you are connected to VNC Server (Enterprise) or VNC Server (Personal), you can exchange files with the host computer.

Note: If file transfer fails for any reason, see Troubleshooting file transfer.

Sending files to a host computer

To send files to a host computer:

1. Click the File Transfer VNC Viewer toolbar button. The VNC Viewer - File Transfer dialog opens on the client computer:

2. Click the Send files button. The VNC Viewer - Send Files dialog opens.

3. Select a file or folder. To select multiple files and/or folders, hold down the SHIFT key.

Note: Under Windows, you cannot directly select a folder. Instead, double-click to open that folder, then click Use Entire Folder. To select multiple folders, open the parent folder and click Use Entire Folder. Note this means other files and folders in the parent folder will also be transfered.

4. Click Open (OK under UNIX/Linux). The VNC Server - File Transfer dialog opens on the host computer:

The most recent file transfer operation is highlighted. You can check its status, or pause or stop the transfer if it takes more than a few seconds.

By default, files are downloaded to the host computer’s desktop (Downloads folder under Mac OS X). To change this for future file transfer operations, select an option from the Fetch files to dropdown at the bottom of the VNC Server - File Transfer dialog. Note you must have write permissions for the folder you choose. Alternatively, you can ask to be prompted each time.

Publishing files to all connected client computers

You can fetch files from a host computer. Note that all other VNC Viewer users connected at the same time as you will also receive the files. To do this:

1. In the VNC Viewer window, right-click the VNC Server icon (typically shaded black) and, from the shortcut menu, select File Transfer. More on this icon. The VNC Server - File Transfer dialog opens on the host computer:

2. Click the Send files button. The VNC Server - Send Files dialog opens.

3. Select a file or folder. To select multiple files and/or folders, hold down the SHIFT key.

Note: Under Windows, you cannot directly select a folder. Instead, double-click to open that folder, then click Use Entire Folder. To select multiple folders, open the parent folder and click Use Entire Folder. Note this means other files and/or folders in the parent folder will also be transfered.

4. Click Open (OK under UNIX/Linux). The VNC Viewer - File Transfer dialog opens on the client computer:

The most recent file transfer operation is highlighted. You can check its status, or pause or stop the transfer if it takes more than a few seconds.

By default, files are downloaded to the client computer’s desktop (Downloads folder under Mac OS X). To change this for future file transfer operations, select an option from the Fetch files to dropdown at the bottom of the VNC Viewer - File Transfer dialog. Note you must have write permissions for the folder you choose. Alternatively, you can ask to be prompted each time.

Disabling and enabling file transfer

You can disable file transfer while the current connection is in progress.

To do this, open the VNC Viewer - Options dialog and, on the Inputs tab, turn off Enable file transfer. More on this dialog. The File Transfer VNC Viewer toolbar button is disabled.

You can enable file transfer again at any time.

Troubleshooting file transfer

If file transfer does not work, check the following:

1. Are you connected to VNC Server (Enterprise) or VNC Server (Personal)? You cannot transfer files to or from VNC Server (Free). For more information, see Connecting to VNC.

2. If you are using a previous version of VNC Viewer or VNC Server, is it at least version 4.4? File transfer is not supported by earlier versions.

3. Has VNC Viewer been configured to disable file transfer? To see how to enable it again, read Disabling and enabling file transfer.

4. Has VNC Server 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.

5. Has VNC Server been configured to prevent you transfering 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 use this feature. For more information, see Restricting features for particular connected users.
