Is my Swift Compare version 1.3 compatible with Windows 10?
It's impossible to say if the software is compatible with Windows 10 or not because no package could be downloaded for installation. I've tried to obtain one from the official website, and a DNS error is displayed instead. This could also mean the domain or hosting is expired rendering the software completely discontinued.
I recommend using other applications that are updated and already available for using on modern operating systems: http://software.informer.com/search/folder+compare
