Uses deflation to compress this file. Deflation is the most effective method, but is not compatible with older versions of some unzipping programs.
Stores files in the zip archive without any compression.
Uses shrinking for the selected files. Shrinking is effective for smaller files since it has a lower overhead than implosion.
Uses implosion for the selected files. Implosion is the second most effective method, after deflation.
Allows ZipIt to determine which method would be most effective for each file. Since deflation is always better than the other methods, ZipIt will only choose between implosion, shrinking, or storing if you choose this option.
