I've tried to select multiple folders and want to rename the word "ft." into "feat." in the file names.
I've selected the folders, clicked for rename, choosed "Find and Replace" and selected 'Case Sensitive', 'Rename files in selected sub-folders' and - 'Test Mode'. After that I press OK and a new window opens with the result.
At first - the settings 'Case Sensitive', 'Rename files in selected sub-folders' and - 'Test Mode' have been removed from the original window. Why? I think that's a bug.
And the result shows the old/new filenames (ok) but also all selected directories which should be renamed to "feat."? Why? They don't include the word "ft.". What's wrong?
I'd guess that both are bugs in the Test Mode code.
The folders don't get renamed, right?
The preview list in the other window of your screenshot shows the folders won't be renamed so presumably it's just the Test Mode output displaying things incorrectly, plus a second bug where clicking OK in test mode doesn't copy the selected options across to the new dialog.
