what function does WinRAR have?

　　 what function does WinRAR have? WinRAR is a powerful compression package manager, WinRAR can backup our daily data, we can download from the Internet compressed package file to extract, but also can be some of our files to compress, thereby reducing the size of e-mail attachments.

Advantages and Characteristics:

* WinRAR uses the original compression algorithm. This allows the software to have a higher compression ratio than other PC compression tools, especially executable files, object link libraries, large text files, and so on.

* WinRAR supported files and compression packet size reached 9,223,372,036,854,775,807 bytes, about 9000 PB. In fact, there is no limit to the number of files for a compressed package.

* WinRAR fully supports RAR and zip compression packages, and can extract cab, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2. JAR, ISO, Z, 7Z, RAR5 format compression package.

* WinRAR supports NTFS file security and data flow.

WinRAR still supports command-line patterns similar to the DOS version, in the form of:

WinRAR "Order"-"switch" "Compressed package" "Document ... "Decompression Path"

A compression, E, X decompression and other common parameters are basically the same as the DOS version, can be easily referenced in the batch file.

* WinRAR provides the ability to create a "solid" compression package, which increases the compression rate by 10%-50% compared to conventional compression, especially when compressing many small files.

* WinRAR has the ability to use the default and external self-extracting modules to create and change the self-extracting compression pack.

* WinRAR has the ability to create a multiple-volume self-extracting compression pack.

* Can establish a variety of ways of the full Chinese interface of the full function (with a password) multiple-volume self-solution package. We know that the inability to build a multiple-volume self-extracting is a major flaw in the WinZip, and winrar handling this kind of work is very comfortable, and the self-extracting package file can also be added with password protection.

Even compressed packets can be repaired because of physical damage and can be prevented by locking the compression pack. Authentication information can be added as a security guarantee, and WinRAR stores information about the last updated compressed package name.

* WinRAR can prevent artificial additions, deletions and other operations, to maintain the original state of the compressed package.

Higher compression rate

WinRAR in the DOS era has been this advantage, after several tests proved that WinRAR's RAR format is generally higher than other ZIP format 10%~30% compression rate, in particular, it also provides a selectable, multimedia data compression algorithm.

A unique high compression rate algorithm for multimedia files

WinRAR to WAV, BMP sound and image files can use a unique multimedia compression algorithm greatly improve the compression rate, although we can be WAV, BMP file into MP3. JPG formats save storage space, but don't forget that WinRAR compression is standard lossless compression.

Zip format can be well supported and can extract multiple formats of compressed packets

Although other software can support ARJ, LHA and other formats, but the need to plug the corresponding version of the software DOS, it is a limited function. But the WinRAR is different, not only can extract most compressed format, and without the support of the plug-in can directly build zip file compressed files, so we do not have to worry about leaving the other software how to deal with the problem of the zip format.

The Setup project is perfect and you can customize the interface

Start WinRAR by starting the program group of the menu, select "Settings" under the "Options" menu in its main interface to open the Settings window, divided into general, compression, path, file list, viewer, comprehensive six categories, very rich, by modifying them, you can better use WinRAR. Actual combat: If simultaneously installs the compression software and the Winrar,zip file association frequently to have the confusion, generally we simply enter the Setup window, chooses "the Synthesis" the label, will "WinRAR related file" one column in the zip one tick, determines then may make the zip file and the WinRAR Association, Conversely, if the check is removed, the WinRAR automatically modifies the registry so that the ZIP is associated with the compression software.

Strong ability to repair damaged compressed files

Download on the Internet zip, rar-type files are often caused by the head damage can not be opened, and with WinRAR, only click the interface of the "repair" button can be easily repaired, the success rate is extremely high.

You can view the compressed package information without having to extract it

Select the file click Information to view the compressed package information.

Accessibility Settings Detail

You can delete the destination disk file before compressing in the Backup tab of the compressed window; You can click the "estimate" button before compression to evaluate the compression, you can add a comment to the compression package, you can set the compression package to prevent damage, and so on the nuances can be seen winrar thoughtful.

The compression pack can be locked

Double-click the "Lock Compression package" under the Command menu to prevent human additions, deletions, and so on, to keep the original state of the compressed package.

Compressed packages can look at hidden files

Are you still worried about the autorun virus? WinRAR provides "perspective" functionality. Put those hidden attributes to the file at a glance.

Using the WinRAR compression tool can help us to browse the compressed package without decompression of the file, but also to the damaged compressed file repair, WinRAR's RAR format is generally higher than the other ZIP format 10%~30% compression rate.
