Hi,
in this list WinSCP is missing:
https://armrepo.ver.lt/
ARM builds of FileZilla are already available (at least unofficially). I like WinSCP very much and I hope WinSCP won't fall behind in future as Microsoft seems now pushing Windows on ARM.
Are there any plans to offer native ARM64 builds? I think now would be a good time to make the source code adaption, as you could use AI tools like ChatGPT, which could do (more or less) the hard work for you.
