File Transfers

This feature shares most of the code with printer forwarding.

This is not meant to replace a network filesystem, it is only there to facilitate the transfer of individual files between the client and server.

For more details, see #494 and #1026.

Assuming that file-transfers are enabled (which is the default - see configuration options below), the client can send files to the server using the system tray upload menu:

The server can send files to the client using: * the `xpra send-file` subcommand * the dbus interface: [#904](https://github.com/Xpra-org/xpra/issues/904) * the xpra control interface, ie: `xpra control :10 send-file /path/to/the-file-to-send`

To send to a specific client: xpra control :10 send-file /path/to/the-file-to-send open CLIENT_UUID
The client UUID can be seen with: xpra info | grep uuid. To send to all the clients, replace use "*". (quoted to prevent shell expansion)

Depending on the client configuration, the open flag may not be honoured by the client.

* `file-transfer` enables or disables all file transfers * `file-size-limit` the maximum size for file transfers * `open-files` allows files to be opened after being received - which may be a security risk * `open-command` the command to use for opening files To debug this feature, use the flag `-d file`
