WinRAR is currently the mainstream compression software. This software is mainly to help users compress and decompress files. For some large files, WinRAR is indispensable when uploading, downloading, transferring, or backing up. There are a lot of features of this software, but many of my friends are not clear, let's introduce Xiaobian for everyone!
Main functions: 1. WinRAR compression rate is higher. WinRAR has always had this advantage in the DOS era. After many experiments, WinRAR's RAR format is generally 10% to 30% higher than other ZIP formats, especially it also provides optional, targeted A compression algorithm for multimedia data. 2. There is a unique high compression rate algorithm for multimedia files. WinRAR can greatly improve the compression ratio of WAV and BMP sound and image files with a unique multimedia compression algorithm. Although we can convert WAV and BMP files into MP3, JPG and other formats to save storage space, don't forget that WinRAR compression is standard. compression. 3, can fully support the ZIP format and can extract compressed packages of multiple formats. Although other software can also support ARJ, LHA and other formats, it requires a DOS version of the corresponding software, which is really limited. However, WinRAR is different. It can not only extract most compression formats, but also directly create ZIP-formatted compressed files without the support of plug-ins, so we don't have to worry about leaving other software to deal with ZIP format. 4, the setup project is very complete, and the interface can be customized. Let's start WinRAR through the program group that starts the menu. In the main interface, select ““Options” under the menu to open the settings window, which is divided into general, compression, path, file list, viewer, and integrated six. Large classes, very rich, can be used to better use WinRAR by modifying them. Actual combat: If a certain compression software and WinRAR are installed at the same time, the association of ZIP files often becomes confusing. Now we just need to enter the setup window and select the “General” label, which will be ZIP of the “WinRAR associated file” column. A tick, after confirmation, can associate the ZIP file with WinRAR, and if it is removed, WinRAR automatically modifies the registry to re-associate the ZIP with this compression software. 5. WinRAR can be used to participate in batch commands by command line. The RAR included in WinRAR supports command line operations on Windows/DOS systems in the format: RAR
- a Compression, e, x decompression and other common parameters are basically the same as the DOS version, which can be easily referenced in the batch file. Actual combat: We edit the following batch file WPS.bat: start /w “c:\\program files\\wps2000\\winwps32.exe” start “c:\\program files\\winrar\
ar” m -p328 c:\\mywj \\wj.rar c:\\mywj\\*.wps After the batch file runs, first call WPS 2000. The user edits the file and saves it in the Mywj folder. After exiting WPS 2000, RAR immediately compresses and adds the password to the WPS file under Mywj. Moved into Wj.rar, eliminating the tediousness of each compression encryption. 6, the ability to repair damaged compressed files is extremely strong. The ZIP and RAR files downloaded on the Internet are often unable to be opened due to head damage. After being loaded with WinRAR, you can easily fix them by clicking the “Repair” button in the interface. High, everyone may wish to give it a try. 7, can establish a full range of full-Chinese interface (with password) in a variety of ways. We know that not being able to build a multi-volume self-unpacking package is a major drawback of some kind of compression software, and WinRAR is very easy to handle this kind of work, and it can also be protected by a password for the self-unpacking file. Actual combat: Start WinRAR to enter the main interface, select the compressed object, select the “Password” under the file menu, enter the password, click OK, click “Add” button in the main interface, and “General” label Under the "Create a self-extracting package", tick, enter the size of each volume in the size of the size of the volume; click the "Decompression package option" under the "Advanced" tab, select the graphics module mode, In the "Advanced self-extracting package option", you can set the title, information, default path and other items displayed during the self-unpacking runtime to determine the compression start. 8, the auxiliary function settings are meticulous. You can delete the target disk file before setting compression in the "Backup" tab of the compressed window; you can click the "estimate" button to compress the compression before you compress it; you can add a comment to the compression package; you can set the compression package. Anti-damage features, and so on, can also be seen in WinRAR's thoughtful and thoughtful. 9, the compression package can be locked. Double-click to enter the zip file, click "Lock zip package" under the command menu to prevent artificial addition, deletion, etc., to maintain the original state of the zip package. The above nine points are the main functions of WinRAR. After reading these introductions, I believe that you will not simply define this software as a compression software. We can use it to encrypt important files, or use it to repair damaged files …… interested friends, let me experience it!
