ArKiwi

ArKiwi, formerly known as Archivaldo, is a lightweight and very fast file archiver, where you can add, compress, extract, delete, password protect, and blazing fast search all your files. in a compact binary file system called ARA (ArKiwi Resource Archive). The ARA file is a file system with the capacity to accommodate theoretically unlimited numbers of files, of any size or type ( jpg, gif, avi, mpg, ogg, mov, txt, mp3, mp3, acc, doc, iso, etc) only limited by the free space available in your hard disk or storage device. Also, you can add or remove files from your ArKiwi archive at any time, ArKiwi will contract or expand dynamically the archive depending on your needs.

The ARA file is a 100% binary file, and because of that characteristic can be stored, modified, saved, read & transmitted by any host system without data loss or its functionality in the process.
