What I exactly did was go into WinSCP and I went on my Wii U and I first went into Homebrew then I opened Mocah then FTPiiU in Homebrew and then my gamepad had a black screen with the ip like 192.###.#.#:21 so I put that into WinSCP and then I logged in anonymously then I navigated to my Minecraft worlds and I have worlds I had to replace so I had the modded worlds renamed to the worlds I was going to replace. I use this method basically https://www.youtube.com/watch?v=jdXYIXMP5Pg&t=539s
Now when I dragged my modded worlds after I renamed then, I got this error
Invalid access to memory.
Please help us improving WinSCP by reporting the error on WinSCP support forum.
Here's a gif of what I did basically. I am on the newest version on WinSCP. I got rid of everything that's WinSCP and then reinstalled it.
