The disk or folder that you share, along with all of the folders that it
contains, will be accessible by other network users. If you're sharing an
entire disk, Windows XP gives a warning. The implication of the warning is
that it's better to share a specific folder, since only that folder (and its
subfolders) will be accessible by others, and the rest of the disk will be
inaccessible. Click where indicated if you want to go ahead and share the
entire disk. This screen doesn't appear if you're sharing a folder.

How Can I Get File Sharing to Apply to a High-Level Sub-Folder and ALL
Sub-Folders with one simple change, rather than having to endure the
incredible tedium of having to click on each sub-folder 4 times or more so
that all folders within a higher-level folder are shared. The it works now
is a major pain. Surely there's a simpler way to do this. I have one
high-level folder with about 400 sub solders and some of them have multiple
sub-folders.
