![]() ![]() Both methods compress at around 1 MB/s on a 2 GHz CPU and can decompress at around 10-20 MB/s on 2 GHz CPU. The program is open source and always free for everyone.ħ-Zip archives files at a very high compression rate, typically in its proprietary 7z format using either its own LZMA or LZMA2 methods. If you need a free zip file opener or for any other compressed file type, 7-Zip is the answer. It can unpack CramFS, NTFS, AR, VHD, CAB, SquashFSCPIO, DMG, NSIS, EXT, ARJ, GPT, ISO, LZMA, MBR, IHEX, MSI, HFS, CHM, QCOW2, RAR, LZH, RPM, UDF, FAT, UEFI, VMDK, Z, WIM, VDI, and XAR. However, you can also store your configurations as a profile for use later to save time.ħ-Zip works on Windows, Linux, and macOS platforms.ħ-Zip packs files in 7z, GZIP, XZ, BZIP2, WIM, ZIP and TAR formats. This feature can be a lifesaver for beginner users in file compression, as the program has a wide range of configuration and security settings. The wizard within the program is great for speeding up the compression process and comes with a virus scanner. But remember that encryption isn’t worth anything if you don’t have a strong password.īesides the wide range of supported formats and security features, WinRAR also has an intuitive interface that allows you to weave between its various functions with ease. WinZip, WinRAR matches the competition with 256-bit password encryption available. However, the program is always speedy when you need to unzip a file and is easily the best RAR extractor. RAR always has a faster compression rate than ZIP when using WinRAR, but its overall compression rate is slower than WinZip or 7-Zip. With WinRAR, you can compress and create either a RAR or ZIP file, and the program automatically helps you to select the best compression method for your file.īased on the type of file and compression you need, tests have shown WinRAR to compress up to 40% of the original file in RAR format. They also have a physical version on CD available for $9.99 per order.Ĭompression rate and file size, compression method The software comes with a 40-day trial and is available in over 50 languages. But it only compresses in RAR or ZIP.Įach WinRAR license costs $29.99 plus $4.35 for the maintenance package, and both are lifetime purchases. WinRAR can decompress a wide range of common formats, including RAR, ARJ, LZH, GZip, UUE, CAB, TAR, ISO, Z, 7-Zip, and BZIP2. The key difference between the two is that WinRAR has a graphic interface, whereas RAR can only run directly from the command line. But they offer software called RAR for Mac and Linux. For some archive types, PK Protect can only extract, not create new archives.WinRAR only works on the Windows platform – XP and later, including 11. The following table lists the types of archives that PK Protect can create or extract from and the file name extensions customarily associated with these types. ![]() If you want to create a new non-ZIP archive, you can select the type you want when you save the archive. If you are extracting, PK Protect will identify the archive type and extract the archive's file(s). You do not need to do anything special to use PK Protect with a non-ZIP archive. A ZIP archive can contain multiple compressed files, and PK Protect can encrypt and digitally sign these files. By default, PK Protect creates ZIP archives. Archive types differ in the number of files they can contain-some can contain only one file, some can contain multiple files-and there are other differences as well. While you will probably work most often with ZIP archives, PK Protect can extract archives using many formats, and can even create archives in some of these other formats. When PK Protect extracts files, it also decrypts them if they are encrypted (if they were encrypted specifically for you, or you supply the passphrase!). PK Protect also extracts and uncompresses files in an archive so that you can work with them again. You can also use PK Protect to encrypt and digitally sign files that you add to a ZIP or OpenPGP archive. As a rule, files that you put in an archive are compressed so that they take up less space, and PK Protect ordinarily compresses files unless you tell it not to. An archive is a file that you use like a suitcase to hold other files. PK Protect is a program for, among other things, working with archives. ![]()
