no probs Lasty ,
The above instructions where how to “create” a *.* folder … but if you want to _ rename _ an existing folder and place a dot in front … you will still need to do it via the cmd … Commanf Prompt.
Here’s how (example … use ren [short for rename] your existing folder … followed by a new name with a dot in front)
cd…
cd…
