[erlang-questions] Best way to check if a given directory is empty (or not)?

[Zabrane Mickael]

Hi guys,

I'd like to know if there's a good and portable method to check if a directory is empty (or not)?
In my case, the directory can contains huge number (more than 150K in average) of files if it is not empty.

I've tested the following working calls:
a. file:list_dir/1
b. filelib:wildcard/2

The problem with them is they both return a list of filenames.
I'd like to avoid getting this list back to be able to check if it's empty or not.

Advices please?

Regards
Zabrane
