NTFS junction points are empty folders that point to the contents of another folder. This option enables you to prevent these folders from being searched and processed. This option is activated by default. When deactivating this option you should check first that no loops are created by the junction points and no data items are processed twice.

Disable Windows 64-bit file system redirection

This option enables AllDup to determine the correct count of all system files on a 64-bit Windows system.
