Problem with empty folders

Hi,

I get an error when I point to an empty folder with sub=”xxxx”.

I get a warning that says:

Warning: asort() expects parameter 1 to be array, null given in /xxx/xx/x/xxxxx/wp-content/plugins/file-away/includes/file-away.php on line 226

Warning: Invalid argument supplied for foreach() in /xxx/xx/x/xxxxx/wp-content/plugins/file-away/includes/file-away.php on line 227

If I upload a file such as a PDF everything works again.

Thanks for a great plug-in 🙂
