The developers of ExtremeCopy claim this program can help you optimize copying speed, especially when you are copying very large files. You will seldom need to use this program’s interface because it integrates with the system to allow you use Windows Explorer’s contextual menu instead. However, should you want to, you can start the program’s main window. Copying via this interface is certainly more difficult than using the right-click option. However, it allows you to take advantage of various useful features, such as applying filters and rules. This way you can set the program to rename files automatically when there is a name conflict or to replace older files with newer ones.
Using this application instead of the built-in Windows utility allows you to benefit from such options as temporarily pausing and resuming jobs or resolving copy conflicts. When tested and compared with the system’s built-in tool, the program allowed me to copy a bunch of files and folders at a greater speed. In general, it is a fine robust application. As there are many other similar applications available and most of them can be tried for free, I suggest you test some of them and make your own decision.
