Unlike other similar apps, which usually only offer single view, this app offers multiple views.
Pro Handles "hard linked" files correctly - doesn't count them more than once
WizTree is faster and much more accurate than all the others as it properly handles hard linked files (doesn't count them more than once) so the total allocated size reported by WizTree will actually match the space used on the drive as reported by Windows.
Cons
Con Folders cannot be sorted by size
Con Cannot access Android device connected by USB
Con Cannot access Android device by FTP
And can never will as this is clarified by developer that this feature will never be added.
Con It doesn't have UNDO function
Very important. When you work with valuable data files, this function can't be ommited.
Con Navigating folders by Ctrl+Tab has considerable delay
Con Browsing Recycle Bin is very slow
Navigating away from Recycle Bin tab and coming back to it reload the Recycle Bin which is very slow as mentioned. Program has an option to open recycle bin in Windows File Explorer, which suggests that developer is aware that opening Recycle Bin is problematic.
Con Confusing
Con Context menu only based on icons
No longer with Onecommander 3.6.43
Con Intended for NTFS only
It'll work with any other file system but with the same speed as any generic space analyzer.
