Access-based Enumeration settings on an NTFS file system have no effect on Filr.
For example, a Windows administrator might disable Access-based Enumeration so that the files in a shared folder always display in Windows Explorer no matter what the user’s rights.
The administrator might then expect that users would also be able to see the files through Filr. That is not the case. Disabling Access-based Enumeration has no effect on Filr. Only those users who have all of the NTFS permissions required for the Viewer role (Read, Read & Execute, and List Folder Content) can see the files.
