Copy++ is a tool software that aims to make copying easier by processing texts automatically, like removing the redundant whitespaces when you copy a PDF file.
What you need to do is just copy and paste. No more formatting texts by yourself after copying.
Free yourself!
There are two versions of Copy++.
One is based on WPF/C# and it's the initial and current version.
Another one is based on Qt/C++. Its biggest advantage is cross-platform. It's still under development and will be released soon.
