File Compression Facility WinZip 7 Zip WinRAR
The most popular file format is compressed ZIP and RAR. The best file compression program for this format WinZip, WinRAR and 7-Zip. However, you should be aware of how to compress a file, before you start using this program. And following the introduction of a compression program.
WinZip
WinZip offers a wizard interface for new users, and the classic interface for experienced users. This allows for lossless compression of JPEG images. JPEG itself is used to compress the image in BMP, and WinZip to compress further by 20 to 25 percent without loss of quality.
WinZip Camera Wizard will automatically compress images, video and audio from your digital camera into a ZIP file. Camera model must be supported by WinZip, and all you have to do is connect the camera to the computer.
WinZip also delete all the zip files from the camera. WinZip features Smart View that shows thumbnail images in a ZIP file, without extracting them. See smart shows directory tree of folders and sub-folders in Windows Explorer style.
WinZip offers an image viewer to view slide shows, rotate, resize or delete photos without extracting them. You can rename files and folders in the ZIP file without extracting them. Winzip allows security features such as setting a password for the zip file.
The system administrator can choose the minimum length of the password (which is usually 8) and the type of character that contains the password (which can be uppercase, lowercase, numeric, and symbol characters). WinZip supports 128-bit and 256-bit AES encryption and decryption. WinZip supports Internet file formats such as 7z, BZ2, RAR, TAZ, GZ, Z, TAR and TGZ by being able to extract the files in this format, but can not create the file.
7-Zip
7-Zip can both create and extract files in 7z, ZIP, GZIP, BZIP2 and TAR formats. This prgram can also extract but can not zip or compress files in ARJ, CHM, CAB, CPIO, DMG, DEB, HFS, LZH, ISO, MSI, NSIS, RAR, UDF, LZMA, WIM, XAR, RPM and format Z.
7z format is 40 percent better than ZIP format. However, compression requires more processing power than the ZIP format. Solid supports 7z archives, which are much smaller in size, but not good enough, if you want to update or access individual files often.
7z also offers a self-extracting archive, which includes stub extract the files without the need 7-Zip. 7-Zip has four compression levels: Fast, Normal (default), Maximum, and Ultra. 7-Zip also has a command-line version called p7zip for Unix and Linux operating systems. 7-Zip archives allow testing after creating it, to check the integrity of the archive and ensure no damage.
WinRAR
WinRAR, one of the best compression tool, is a 32-bit program and very good for multimedia compression, because choosing the best file compression method. WinRAR allows you to change the directory through the Panel Folder Tree. RAR format compresses files by 8 to 15 percent better than ZIP format.
RAR extractors are also easily available for free download. WinRAR has a built-in virus scanning. However, decompression speed is slower than the ZIP format. WinRAR also decompresses files from TAR, BZ2, ACE, ISO, JAR, and ZIP format.
WinRAR has had Unicode support for international characters in file names, and also supports long file names. Also fixes WinRAR from corrupted RAR files. WinRARsupports file locking, to prevent modification of files, so that other people can not change the contents or comment in compressed files. WinRAR allows the creation of self-extracting file, which ended with an EXE extension, so the end user does not need decompression software to extract the files.
WinRAR has the option to encrypt files using AES (Advanced Encryption Standard), to ensure the security and privacy of the file. WinRAR provides a way to remove or delete the temporary files. WinRAR also has a feature to verify authenticity, which adds information about the creator of the archive. WinRAR can search for text in the archive.
General Function Winrar
There are many functions of Winrar. However the, usually computer users often use Winrar to do some of the following. Compressing files. If there are many small files that are sent or copied (usually via email or flash) can cut the time to unify the file in the form of Winrar. So we did not bother with many small files that are sent or at-sharing.
Winrar is also often used for compress the file. File when resized into winrar then size will be lighter or smaller. More make file to be safe. In winrar there is a menu password. So that when the file is converted into winrar we can use the password. When it will open the winrar file we must enter his or her password. Thus not everyone can open the winrar file. Only we can.
Dividing or splitting a file. If there is a large file that will we save, but space is limited, so with winrar we can break it or share it. Suppose we have a file with a capacity of 4 gigabytes. However, our storage media only 2 gigabytes. With winrar we can split it into two parts of the file. So that each file will be sized 2 gigabytes.
Winrar can be used to extract the files or break package winrar files. That is, when there is a winrar file extension (usually files downloaded from the internet) then we use winrar to open it. And the file will be broken down into several sections.
Winrar can also prevent our files from computer virus threats. Usually winrar file extension will very rarely infected computer. This is in contrast with the original file is not compressed to winrar. As the files .exe application.
