Is there a way to retrieve certain metadata of a file such as file size?

Question

Looking to see if there's a function like the below:
qie.getFileName();

In which I can retrieve the size of an associated file.

The source connector is an FTP retriever.

You can use the length property of message.getBytes() to get the size of the current message in bytes.  For example, the below would store the file size in a variable called fileSize:

var fileSize = message.getBytes().length;
