Given the folder structure below:

file.txt
0/file.txt
1/A/file.txt
1/B/file.txt
2/file.txt

The action Directory_ListDirFiles from NetworkFileSystem returns the following:

file.txt
0/file.txt
1/A/file.txt
1/B/file.txt

Once it entered the folder 1/, it searched the subfolders within 1/** and couldn't find the folder 2/ at root level.

Is this a bug? Are there alternative ways of listing folders in the file system?
