1. Oracle NetSuite Help Center. (2023). Restricting Access to File Cabinet Folders. SuiteAnswers ID: 9911.
This document states
"When you restrict a folder
all of its subfolders are also restricted. If you later change the parent folder's restrictions
the subfolders inherit the new restrictions." This directly supports option D. It also confirms that restrictions are applied to folders (refuting B).
2. Oracle NetSuite Help Center. (2023). Making Files and Folders Available Without Login. SuiteAnswers ID: 9910.
This document notes
"For security reasons
the Available Without Login box is not checked by default." This directly refutes option C.
3. Oracle NetSuite Help Center. (2023). File Cabinet Overview. SuiteAnswers ID: 8959.
This document outlines the structure and functionality of the File Cabinet
explaining that permissions are managed through folder settings
which implicitly refutes the concept of restricting individual files (B) and the existence of a "Company-Wide Usage" box on a file record (A).
