Sometimes, when you download files from Usenet, the binary files are cut into several pieces. Thus, to merge them, you need a tool like AutoUnpack. This software can merge the pieces to reconstruct the original file. To do this, you only have to localize the folder that contains your files and to define the target destination so that it can do the rest. Via its interface, it can show you the progress of the operation; in addition, it can also be used to download, to repair and to decompress RAR, 7z, ZIP and TS archives.
