Past year wnen I copy a folder let say 'TestFolder' to some other place where
same folder exist I got followin options:
1. Skip
2. Change the name
3. Copy into
Plus a check box 'Apply to all'

This allowsd me to check the option 'Copy into'.
Then dialog again shows a form where again shows the same if under my top
folder 'TestFolder' there is anoder folder already available in the
destignation place.

Using this one can update some information in the destignation folder making
Dolphin to copy in the folders only the files and folders not already available
in the target place.

Unfortunately after some updates the third option 'Copy into' get missing.
Because of this I must change the name of my 'TestFolder' in order to make
possible to copy it to the target place.
So I can not copy the only new files available in my source folder 'TestFolder'
but must copy all of it.

I can not understood how this get so. May be because of some change of kdelibs,
or may be by upgrade of the Dlphin or may be some interference may occure with
the KDE5?

Especially for me and my colleagues this 'Copy into' option was the most
importand functionality of Dolphin. So now all our workflouw is distroied now
because we must copy a lot of information for backups twice and we waste a
hudge time for it.

My current wersion of Dolhin is 14.12.3 KDE Development Platform 4.14.3
