At Roland-Garros last year, Kenin shot to fame when she beat Serena Williams in the third round only to lose to the eventual champion, Barty.
That win started the change in the way she perceives clay and the American says she now knows what it takes to succeed on the surface.
“I feel like last year I started to really like the clay after my great run,” she said. “I played Serena. It was obviously a lot of emotions as well there. Yeah, after that I started to really like the clay.
“I knew what to expect. It's a lot of sliding, it's very physical. I just tried to adjust my game to it. I feel like as each match went, I'm more and more comfortable on the clay.
“I'm super proud to be in the quarter-finals. Because this used to be a surface that I really don't like. Now it's obviously a surface that I really enjoy playing on.”
This time, she takes on either Ons Jabeur of Tunisia or American Danielle Collins, whose match was held over until Tuesday because of rain.
“Jabeur I've played quite a bit,” she said. “I've beaten her all the time except one time. I think it's 5-1 or 4-1. I forgot the ratio. Yeah, I played her last time at US Open. It was a really tough match. She's obviously playing some great tennis. She's a really tough player to play. She's got a lot of variety. She's very tricky. It's going to be an interesting match.
“Against Danielle, I played her in Adelaide. She played a good match. I didn't feel like I could get my rhythm. I lost. But we'll see how it's going to go. She's obviously playing well. She's aggressive. Yeah, I'll just see what's going to happen.”
Ferro, whose ranking will rise to No.41 after reaching the last 16, said she felt Kenin raised her game when she needed.
The Frenchwoman was disappointed to see her eight-match winning streak come to an end but said she enjoyed being out on Court Philippe-Chatrier.
“It was amazing,” she said. “I would have loved that it lasted longer. But I am a bit sad to lose today. This is what I practice for, for moments like this. I was lucky to play three matches on the centre court. It was an unbelievable experience for me. I will do everything to be back as soon as possible.”
