Cons
Con Keyboard shortcuts not editable
Con Slow
In my opinion, it's slower than Filezilla.
Con No x64 version
Con Does not support UNC
Does not support UNC. This makes working with the "Library"-function in Win 7, 8, 10 not possible when working over a network.
Con Weird keyboard selection handling
If you are accustomed to several commanders, the selection method in WinSCP behaves unexpected - most often selects too much.
Con No public download
They require your personal data and a working email before you can get the program. Not a great way to spread your allegedly "free" tool.
Con Its Solarwinds, biggest private data leaker
Trust your ssh session to it? No.
