Question / Problem
The radio box "Make Treesize column in Explorer Details View available " is not active.Explorer Context Menu is enabled, but Explorer Column option is "greyed " out. Why can 't I enable this feature ?
Answer / Solution
Are you using Windows Vista? Unfortunately the Explorer column is not supported under Windows Vista because Microsoft removed the interface for adding columns to the Windows Explorer.
The Explorer column is not supported on 64 Bit Windows XP/2003 by TreeSize V4 but will be supported by TreeSize V5.
