Select the directory to extract the file to, and click Extract. Open the zip archive in reference. From the main screen you can select which files to extract. Then press Extract. See the section titled System Requirements for details on this requirement.
Files extract at the same speed regardless of the compression method used.
Compressing files is a mathematically intense process and the tighter you want the compress the more time and processing cycles it will require to accomplish the task. Let's say you have twenty of them that you want to ftp to a location. Instead of moving twenty files you can instead them as one file by first zipping them with zero compression. The Freshen option causes WinZip to update files already in the archive that match the specified files. The Update option is the same as Freshen, but adds any specified files that are not already in the archive.
