You need to configure a folder that allows everyone in your department to view and edit the files in the folder. You also need to ensure that users outside the department cannot access the files…

Granting access to a single user would not meet the requirement of allowing "everyone in your department" to access the files.

Granting only "read access" would allow department members to view but not edit the files, which contradicts the requirement to "view and edit."

Placing files in Windows public folders makes them accessible to all users on the local machine and potentially over the network, which violates the requirement that "users outside the department cannot access the files."

Using the "Share With" menu in Windows allows you to grant specific permissions to individual users or groups. By granting read/write access to all members of the department, they can view and edit files, and by explicitly defining these specific users/groups, you ensure that users outside the department, who are not included in the share permissions, cannot access the files.
