That is the path i used in testing on my machine, you would edit it to the path of the folder where your files are, i presume `/csv_files/`. Maybe you could look at links provided to get some answers.

The file name of the downloaded file is the entire path and I would like it to be only payload.file.

Have you attempted to change the msg.filename after the file read node?  
Try googling `split file name from path using javascript`. you may learn something.

I don't know how I tried this way and got undefined.

```auto
msg.filename = msg.payload.file;
return msg;

```

Let me [google](https://letmegooglethat.com/?q=split+filename+from+path+javascript) that for you

Remember you are using msg.filename , not msg.payload.file.

```auto
var path = msg.filename;
var parts = path.split('/');
var filename = parts[parts.length - 1];
msg.filename = filename;

return msg;

```

I did it this way and it works so far.
