How To: Find out if a directory is empty

CMD Batch script to show if a folder is empty.

@Echo off
Setlocal
Set _folder="C:\Demo"
For /F %%A in ('dir /b /a %_folder%') Do (
    Echo The folder is NOT empty
    goto :ok
)
Echo The folder is empty
:ok

The script above will scan all files in the folder, which may be slow if there are many thousands of files, but it does not recursively scan through all the subdirectories, if a single subdirectory is found, empty or not, that is read as the parent directory is not empty.

To ignore sub-directories and only report an absence of files, use the alternative below, this excludes directories even if they have a period in the directory name:

@Echo off
Setlocal
Set _folder="C:\Demo"
dir /A:-D /B %_folder% >NUL 2>&1 && (
   ECHO Source Folder is NOT empty.
   goto :ok
)
Echo The folder is empty
:ok

In the examples above, the directory name is not case sensitive.
