Time required to compress this folder : 6 minutes and 10 secondsĪmazingly, only Winzip 12.1 able to compress jpeg files effectively. Time required to compress this folder : 5 minutes and 37 seconds Time required to compress this folder : 3 minutes and 51 seconds Time required to compress this folder : 4 minutes and 16 seconds
Source folders is a 300 MB folders, consist of 157 JPEG files. Let see how good Winzip 12 compare to other file compressor.Ĭompression Configuration : Best possible (still same as above)Ĭandidate Version : Exactly same as above screenshot To be fair to Winzip 12.1 which their developer also claim that Winzip 12 now has better algorithm to compress JPEG files, I decide to run another test which is compressing a folder which is full of JPEG files (pictures from my Olympus pocket camera and Nokia N73). 7zip able to compress file 2x better than winrar, but it also need 2x more time compare to Winrar J If size does matter, I full heartedly choose 7zip. Winzip compress time still bearable (68 seconds) which is 3.4x more than WinRar but what interest me here, 7zip doesn’t fall behind Winrar too much. In other word, with almost identical compress capability, Winrar is 8.3x faster than WinAce. While Winace require 166 seconds to do the very same job, Winrar just need 20 seconds to complete this task. However, among all these candidates, if compress time is your concern than Winrar ace this test. 7zip can compress almost 2 times better than winrar and winace and amazingly, more than 3x better than what Wizip 12.1 (with zipx enable) can achieve. And yet, 7zip is an open source and completely free software.
Time required to completely compress this folder : 1 minutes 8 seconds.įrom this simple test, clearly 7zip still the best files compressor. Time required to completely compress this folder : 20 secs Time required to completely compress this folder : 2 minutes and 46 secs Time required to completely compress this folder : 42 secs Notice that size on disk almost 20 MB more than actual size which indicate a lot of under 4 kB files in this folder. Consist of 7448 files (from sql, text, bin, exe, aip etc). So, I guess it would be nice if I could compare Winzip, Winrar, 7zip and WinAce best compression algorithm.Īn OsRose Dev Rev 358 folders. Furthermore, Winzip just launch their latest version of Winzip, known as Winzip 12.1 and according to their web, they are pretty confident with Winzip latest algorithm (zipx instead of good old zip).
However, due to not so proper method that I used in that short test, the result is questionable. Depending on the level at which the encryption is applied, you may have to enter the decryption password to show the folder and file names of the archived elements.Couple of months ago, I posted a mini article regarding Winzip vs WinRar and 7zip and found out that 7zip beat em’ all. If required, 7-Zip encryption can be used for individual files or entire directory structures. It can also extract program archives like Microsoft Cabinet, Windows Installer files and application files. The zipping program can also unzip archives with the endings. 7-Zip also allows users to zip and unzip files in the following file formats:ħ-Zip uses a powerful proprietary encryption algorithm to compress files, sacrificing compression speed for compression quality. It is purely a container format with a modular and open structure. The WinRAR alternative creates zip archives in the proprietary 7-Zip format, indicated by the file ending. In 2007, the program won SourceForge’s award as best open source project. 7-Zip is freeware for zipping and unzipping files and has been around since 1999.
