The Softaken Archive Converter Software is one example of an archive converter for Windows (32-bit and 64-bit). The archive converter allows for batch processing, so you can load a folder full of ZIP, RAR, 7Z, or TAR archives, and convert it all at once, into any of the supported formats. The archive converter retains folder hierarchy and the metadata of all the files too, and works offline as a standalone application with no limit on size for large business-sized files.
