  • Proven UPX binary compressor
  • 7-Zip compression of archives
  • Multiple compression levels

  • Automatically skips <4K files (no space savings)
  • Add inclusions/exclusions using Format
  • Compression of DLL, EXE, ZIP, JAR, IRC, PYD and BINs in all directories
  • Automatically skip launcher if selecting Format apps' base directory
  • Automatically excludes Visual C++ runtimes and Qt image handlers
  • Saving up to 50% or more installed space of many apps
  • Faster application starts from flash drives
  • The same technology we formerly used in Portable, Pidgin Portable, GIMP Portable and more!

App Notes

Helpful tips:
  • Don't compress NSIS launchers (FirefoxPortable.exe, etc), they'll break
  • It's best to have the app you're compressing reside on a hard drive (at least temporarily) rather than a flash drive to improve performance and decrease writes to your flash drive
  • You can disable the Welcome screen or have the console window stay by editing the settings.ini in the Data directory
  • Only NRV2E should be used for Releases (including development tests and pre-releases) unless it's a small app (one exe and a dll or two) and very easy for you to test every feature and function on every Windows OS.
  • Always back up your files before using this tool as it will not work with all applications.
