```auto
let a = "/path/to/file/";
msg.file = a + msg.payload.file;
msg.payload = "";
return msg;

```

Then in the file node use `msg.file`, and uncheck add a newline to each payload.

Perfect works very well thanks.  
another question if i can how do i make the variable  
global "msg.file" so that it can also be used in another flow or even on blocks that are not directly connected to each other

You can global.set in the function before returning message.  
This is explained in docs  
[https://nodered.org/docs/user-guide/context](https://nodered.org/docs/user-guide/context)  
[https://nodered.org/docs/user-guide/writing-functions#storing-data](https://nodered.org/docs/user-guide/writing-functions#storing-data)

Or you can use a change node to set global.file to msg.file
