How to reproduce:
* Add a dot to the folder name, e.g. "Debian 7.8 Wheezy"
* Copy and paste this folder to the same location

Now the new created folder will be named "Debian 7(Copy 1).8 Wheezy"
(This bug does not apply to hidden folders which start with a dot.)

While this would be correct and a meaningful behaviour for files I think it's misleading for folders.

In my opinion the correct result should be "Debian 7.8 Wheezy (Copy 1)".


Kind regards
