The "enhanced deflate" method is similar to the original deflate but operates on larger chunks of data at a time, often resulting in improved compression. WinZip 12 and later no longer uses Fast and Normal when compressing files, but it can still extract files compressed with any of these methods. These all used the same basic technology but were optimized in different ways for speed vs. Therefore it will generally compress your files somewhat faster than Legacy, but the compressed files will be somewhat larger.Įarlier versions of WinZip supported four variants of the deflate algorithm, referred to as Maximum (portable), Fast, SuperFast, and Normal. It is the same basic algorithm as is used for Legacy compression (see above), but is optimized for speed rather than compressed size. This is a good, general-purpose compression algorithm known as "deflate". Therefore, to save time, it may be best to select None or No compression when you are adding a group of files that are already compressed. In most cases, these types of files cannot be further compressed to any significant degree by the available methods. For example, many multimedia and sound files, such as avi and MP3 files, are precompressed versions of images and sound. Some files that you may want to add to a Zip file are already compressed. Here is additional information for all of the compression methods supported by the current version of WinZip: Additional information on specific compression methods zipx files, respectively.įor more detailed information on each of the compression methods, see the Additional information on specific compression methods section below. Set the appropriate compression method in the. Setting the compression method is accomplished on the Zip tab of the WinZip ribbon. In the WinZip Ribbon Interface, you will need to select the appropriate compression method to use prior to beginning the zipping process. In making a choice of compression methods, there are several things to consider, including the type of data you are compressing, your plans for later unzipping the data, and the amount of time you are willing to wait while your data is being compressed. That is all you need to know about compression tools for now.WinZip ® provides several methods for compressing the files that you add to a Zip file. Personally, I have been a long-time WinRAR user but looking at these objective truths I have switched camps and have become a 7-Zip enjoyer. If you do not use anything and need to make a quick decision on which tool to use then you should most likely use 7-Zip because it is free and does a better job at compressing your files while also being in constant development and improvement. If you on the other hand are already using 7-Zip, then there is no objective reason for you to bother switching to any other compression tool. If you are used to WinRAR and you enjoyed it, you can keep using it. WinRAR – faster compression rates while using a lighter algorithm, but is paid software and results in larger files.ħ-Zip – slower compression rate and requires more resources but results in smaller files with better compression and is completely free.īased on these conclusions it really just depends on what you prefer and what you have been using prior to reading this article.
