Custom Compression Settings for Zip

When creating a Zip archive you can change the settings for compression method and compression level.

Compression Method When you create Zip archives you can choose between two different compression methods, Deflate and Deflate 64. Typically, you will want to use the Deflate compression method as it is most compatible with other zip programs. Use Deflate 64 when you need to create zip archives that are more than 2Gb is size.
Compression LevelYou can set the compression level for Zip compression between 1 and 15. At level 1 compression will be very fast, but the archives will be larger. At level 15 compression will be very slow, but the archives will be very small. Changing the compression level has no effect on the compatibility of the archive with other zip programs.
