Best File compression

First, we installed Bastion and compressed its folder — about 863 MB in size of music, graphics, executable files, and various different types of documents:

  • Zip (Windows 8.1): 746 MB (86.4% of the original size)
  • Zip (WinZip): 745 MB (86.3% of the original size)
  • RAR (WinRAR): 746 MB (86.4% of the original size)
  • 7z (7-Zip): 734 MB (85% of the original size)

Next, we compressed Hotline Miami, which is 654 MB of data:

  • Zip (Windows 8.1): 316 MB (48.3% of the original size)
  • Zip (WinZip): 314 MB (48% of the original size)
  • RAR (WinRAR): 307 MB (46.9% of the original size)
  • 7z (7-Zip): 301 MB (46% of the original size)
