How do I delete my ENTIRE list of Skype Contacts.

Skype version: 8.61.0.87

Application version: 15.61.87.0

From day ONE, and I have been using Skype for so long I can't remember, I have had like 6 people that I wish to have on my Skype list.

Over the years you guys have merged my entire list of Hotmail contacts, and everyone I never wanted to hear from into the list. And over the years I have been struggling with how to get my list back to SIX.

I have hit my boiling point with the version that just "updated" itself.

Because it told me to "manage my list of contacts" I should go to Contact Settings. When I go there, there is no way to delete the contacts. I have right clicked before, MANY TIMES to individually clear the list of HUNDREDS of contacts that show up, because I could never find the way to delete multiple contacts or filter out ONLY the contacts I wish to see.

I don't want to only see my active contacts, I WANT ALL OF THEM GONE, with only six remaining. And they continue to re populate.

QUESTIONS:

1. How do I delete ALL of them at once. And only leave behind the 6 I want?
2. How do I empty the RECENT CHATS list that contains hundreds of chats going back to 2016. I don't want that information displayed I want it gone.
3. how do I delete the RECENT CALLS list? Same thing it is miles long and I do not want that information located anywhere, I want it erased.

If I sound frustrated I AM, this is basic functionality that is impossible to find the answers to without coming to a forum. These options should be easy to discover. 

Thanks.. JF
