Use #7Z if you want to: * Update an existing archive quickly * Backup a folder to a storage location * Create or extract a protected archive * Increase efficiency by using archiving profiles Ark (2.6.3) is handy but it doesn\'t seem to: * Create archives with passwords * Extract (some) archives with passwords * Update existing archives by default #7Z is a simple application that attempts to fill these voids. It probably won\'t become a total archiving solution. For installation instructions, see INSTALL.txt. If you encounter any problems, see ISSUES.txt and send me an email if necessary.
