Bit Copier is an alternative to the windows copier. The difference is the more options you get when using this, you get the ability to choose the buffer speed, the option to copy empty folders or not, and the ability to keep copying even when an error occurs.
The program is no longer developed, but last version, 22.214.171.124 Final, released in July 2012, can be still downloaded from the official website.
CopyFolder 1.4 provides many options for copying the contents of one folder to another. Subfolders can be filtered by paths, names or patterns. File names can be filtered by patterns. Files can be filtered by paths, dates, sizes or attributes.
