I don't like this behavior, it may create unwanted duplicates.Important changes and bug fixes in the release 746
- Changed: Rename operation on Vista+ - auto rename file if an item with the target name already exists
I think there should be a confirmation dialog, if the user want to rename the file or not, because the file is renamed to a different name than expected.
EDIT: Perhaps even 3 options:
- rename to a different name ("... (2)")
- skip
- overwrite the file
Default action (focused button) should be "Skip".
OK, I think it's a bug, moved to "Bug Reports".
