Supercopier is an Open Source file management tool that allows you to quickly and easily move, transfer, or copy files.

It was designed as a replacement for the standard Windows file copy dialogs. It will allow you to make large transfers at once with many options including pausing a file transfer, speed limits, on-error resume, error/collision management and seamless management of multiple tasks.

Supercopier supports plugins and multiple languages. The program is free but they do accept donations.
