Thank you very much, Mofi.

So justs show the duplicate (identical by file contents) folders. And additionally the differences of folders (with different names), so the same how UC shows the differences between folders with same names.
Mofi wrote:Sorry, but currently latest UltraCompare v17.00.0.23 does not support such a folder compare with automatic detection of renamed or moved files and folders. I'm also not aware of any folder comparison application having such a feature which does not mean there is no such application, I'm just not aware of any.
Yes, I do not know any either. The closest to get there is to use duplicate search programs, but they do not show equal folders only.
Mofi wrote:Of course the Find Duplicates feature can find files with equal file contents but having different file names because of file being renamed on either side or being a copy with a different name or being located with same or a different name in a different folder because the folder was renamed or the file was copied into another folder.
Yes, such programs find every file with same contents but unfortunately they do not display folders identical by content.

While it is no problem to find out duplicate files, I failed on my test cases to really get a suitable comparison display which displayed right what I have really done before on the two folder trees.
But why should one (the program) know what the user has done / does? The program could just find out the current state. When it finds a file or a special amount of files with same contents, it check if they belong to a single / special folder / it just displays the folders having identical contents. Or it checks the size of folders and after, if the size is the same, checks the content of folders with same sizes. If each file has a duplicate file by content in the other folder the folder is identical by content.

Actually I would think it is not supported because there is no need for such comparisons, may be.
Is it right:
UC can show only folders with same names and identical content (same file names, same file content, same amount of files) as equal.
UC can not show folders with different names and identical content (same file names, same file content, same amount of files) as equal.
UC can not show folders with same names and same content of files with one different file name or more and same amount of files as equal.
Many thanks again
