Powershell script that that lists and deletes (after confirmation prompt) node_modules and .next folders in a folder/directory. Needs more testing.

zListNRemoveNmnx.ps1

# This script seems to be working in some limited tests I did. But it needs more testing before regular use.
# I don't have the time now for more testing.
#
# Lists AND attempts to delete folders/directories (with confirmation prompt) 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 and (attempts to) delete. 
# 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.
#

Detailed description: Powershell script that that lists and deletes (after confirmation prompt) node_modules and .next folders in a folder/directory. It goes into subfolders and is not limited to current directory. This script seems to be working in some limited tests I did. But it needs more testing before regular use. I don't have the time now for more testing.
