[PD] Testing whether a directory is empty without printing error messages if it is

[Matteo Sisti Sette]

Hi,

I'm using [folder_list] to perform the following tasks:
- check whether a directory or file exists
- get the list of files in a directory (which is an empty list if the 
directory is empty)

However, when the file does not exist or the directory of which I'm 
getting the list is empty, it prints an error message on the console. 
The test works, but I need to avoid printing error messages when there's 
no error to worry about.

Is there another way of getting a directory list without printing an 
error message to the console if the list is empty?

Thanks
