ZipBuilder is an advanced compression and management tool for RAR and ZIP archives. ZipBuilder lets you add files to, extract and remove files from, and rename and test your RAR and ZIP archives, as well as create self-extracting archives, repair defective ones, and compute the output size before the actual compression. You can use any of the eight built-in compression methods, store NT security file flags, take advantage of the drag-and-drop capability, and split large files into smaller parts. The program also supports CD-R, CD-RW, JAZZ, and ZIP drives, as well as multithreading.
