Supercopier is a freeware for windows that gives users more options while copying files in Windows. Teracopy is a similar app but that won’t give many options for users and some of you reported that it some time screws up the system. Supercopier gives an option to control the speed of the copying process, you can limit copy speed in configuration.
Supercopier is a tiny app with features like transfer resume, copy speed control, copy list editable while copying and allows you to save/load a list of files to copy. You can setup an errorlog file for debugging later. You can also setup options on what to do when it encounters errors or if the file already exists etc. [Download Supercopier]
