WinMerge appears outdated when used in combination with tools like RoboCopy, as it often can't compare the results. For example, the user copies a folder from an old NTFS disk to a new NTFS disk:
RoboCopy "A:\example" "B:\example" /E /DCOPY:T /IS
After this, there is an expectation that WinMerge can compare the same folders, but this is not the case. This can be for reasons like:
These are perfectly valid for NTFS (limitations apply for File Explorer, not for NTFS), and tend to accumulate over a lifetime. RoboCopy copies them fine. They are on the disk. Shouldn't WinMerge be able to compare them?
Currently, WinMerge lists such files with a red error symbol and an empty Comparison result field (although it shows the correct Left Date and Right date).
