Hi Lindsay,
Yes, this was implemented sometime in 2009. If you have a release newer than 2.3.2.9, you can add
<add key="AllowAdminsToUseDataFolder" value="true" />
to your user.config and then Admins will be able to browse the /Data directory.
Be sure to open the web.config, add a space to the bottom and then save it. This will cause your website to restart which is required to re-read the user.config.
HTH,
Joe D.
