WSH Browser help

I need a WSH that allows me to browse folders on a specified drive ' ' which means I need a couple Inputs: Drive letter and folder names to be browsed ' ' that Returns the List of files/folders in specified folder, various messages ' as appropriate, log file of folders specified for browse.

I broke it down to these:

get drive letter via parameter OR input box
check for drive exists
check for drive ready
check for folders in root of drive
list folders
limit list display to 20 folders
ask for folder to display
check for valid folder name
display subfolders in requested folder
display message if no subfolders exist
limit list display to 20 subfolders
display files in requested folder
display message if no files exist
limit list display to 20 files
ask for repeat of script
create folderlog.txt to track activity
folderlog.txt cleaned out with each use

Can anyone help me with the code for this?
Thanks so much!
