If people didn't know the answers no one would ever
ask very much and this would be a very boring group.

Good.

Not exactly.

First, although it is common terminology these days,
using the word "Folder" when discussing Permissions
is NOT a good way to discuss or even think about them.

Instead use "Share" (or "File Share") when you speak of
offering a resource on the network and use "Directory"
and File permissions when speaking of the NTFS permissions
on each such item (you can also say, "Share" and "NTFS"
permissions but it is IMPORTANT to separate the two
concepts because they are different and lead to confusion
if you confound them.)

Granting permissions to the directories and files (NTFS) is
one step, and granting permissions to the Share (if you need
network access) is a separate step.

Granting permissios to ONE GROUP does nothing to affect
the permissions given to another group -- they are cumulative
-- UNLESS one of the groups DENIES access.

So if you Deny "Users" you cannot grant access to (virtually)
anyone, even admins. But if you give (positive) permissions
to a group, and then to another group, then member of either
group get precisely what you grant -- or the combination if
they are members of both.

BTW:
"explains ....belongs to another group" -- makes no sense
as there is no such dialog or error to my knowledge. Be
very explcit about where you see this, when, and the speficic
wording.

Just do it and use NO "Deny" permissions.

Now the members will have permission to the share
in GENERAL but no actual permissions to any file or
directory (NTFS) on that share UNLESS you have also
given those NTFS permissions to them through the same
or another group to which they belong.

You can even call me if you are completely confused.
