I have a bunch of excel files in a folder (located on a shared network
drive), accessed by different users. Is there some way to restrict access
to
these files to only those users who create a user name & password. In other
words is there a way to have an opening screen ask for username & password
&
only then allows users to access the files?

If these files were in a single directory in a shared network drive, it
should be possible to restrict any access to that directory to members of a
particular named group of users on the network. Then assign all intended
users of the files in this directory to that group. Once these users have
logged onto the network, they'll have access to the files. No other users
would have access to them. Would that suffice?
