# Lists folders/directories with names matching $ListFolders array elements (currently: node_modules and .next), | |
# in a user specified folder/directory or current directory. It also provides a total count of the folders it lists. | |
# It ignores subfolders within the matching $ListFolders array elements (node_modules and .next) it finds. | |
# It also ignores folders present in $ExcludeFolders array (currently: .git). | |
# Usage: script-name [optional-path] | |

# The script uses Get-ChildItem calling it recursively. | |
