Use 7-zip instead of charged WinRAR and WinZip [Z]

Prepared by: xbeta version: 070706/070317 by: making good use of soft http://xbeta.info

7-Zip is a great compression software: Open Source, free, multi-language, extremely small, stable and powerful, and high compression ratio. It is my preferred tool for processing compressed files.

The software name is 7-zip. Try not to write it as 7zip or 7-zip. The file format is 7z.

[1] official introduction to 7-Zip

The 7-zip compression software has a very high compression ratio.
The 7-zip software is released based on GNU lgpl and is completely free of charge.
Main features of 7-zip:
-Updated the algorithm to increase the compression ratio of the 7z format.
-7-zip: software released under GNU lgpl

-Decompression only: rar, cab, ISO, ARJ, lzh, CHM, Z, cpio, rpm, Deb, and NSIs
-For Zip and gzip formats, 7-zip provides 2-10% higher compression ratio than PKZIP and WinZip.
-In the 7z format, you can create an auto-release (SFX) compressed file.
-Integrated Windows Shell Extension

[2] use 7-Zip instead of WinRAR and Winzip

① 7-Zip is free of charge; winrar/winzip is charged (winrar ￥290) or pirated (legal risks and moral losses). For details, see WinRAR vs WinZip vs 7-Zip.
② 7-Zip is smaller. Small performance.
③ When a compressed package is not sent to others, it is stored in the 7z format, and the compression rate is higher.
④ Open source, I like it.

Among them, 1 is the decisive factor, and 2-4 is the plus factor.

[3] experiences

-In fact, I used TC to compress/decompress and use 7-Zip more. If you compress a bunch of files and copy them to others, I will directly use TC, alt + F5. If a compressed package is generated in the current directory, I may use 7-Zip.
-For some so-called installation files in the exe format, I still try to use TC TO OPEN (ctrl + → ). If not, try 7-zip again.
-All files sent to others are in the zip format. rar format is not required, and 7z format is not recommended.
-How can I handle 7-zip without reading rar comments? For the vast majority of software, please download them from the official website or the most formal website. They rarely use the rar format, and do not write important information into comments.

-Use 7-Zip to generate a package or split the file. Add to compressed file → input volume size. Note that the unit is byte. If it is 1 M, enter 1024000. Of course, we can also roughly think that M is 6 0.

-When sending attachments to E-mail, In the TCOR resource manager, it is more practical to compress the shortcut menu to xx.zip and mail it.

[4] about direct compression to zip format

The 7z format has a higher compression ratio, but zip is more common after all. Therefore, I will send a file to someone else, using 7-Zip, but I want to generate a zip format. In earlier versions, the right-click menu does not have the "generate zip" option. The dialog box is required, which is inconvenient. For this reason, there is such a method (link ). This option has been available since version 4.43beta.

[5] supplements from networks and netizens

MSI and chm: 7-Zip also secretly supports the MSI (Microsoft installer file) and CHM (Microsoft Help e-Book) file formats invented by Microsoft, despite poor support for MSI, however, supporting CHM can help me a lot: saving a CHM restoration breaker!
More secure passwords: There is a zip unencryptor on the Internet, but there is no 7z unencryptor.
File Management: After some research, he found that his unique double window function (F9), combined with the custom favorites (this function is available in WinRAR), can easily implement the following features: the resource manager is used as the manager for copying and displaying files. It supports sorting, size icons, and list display. The file icon, right-click, and resource manager display are no different, perfect transition (required); detailed progress and speed prompts when copying files, far better than Expleror! After the window is closed, the current path will be remembered next time. With the shortcut key, you can quickly switch folders and define 10 folders.

Default solid Compression: By default, "solid compression package" is used for 7-Zip compression: the similarity between compressed files is also considered, that is, the content of all files is compressed as a whole. Therefore, the overall compression rate is high and the compression speed is slow. The associations between compressed files also bring disadvantages: Even if you extract a file from a large compressed package, you must first decompress the dependent associated files. In addition, if a byte in the 7z file is accidentally changed, most files may fail to be decompressed. 7-Zip can also be used without the "solid compressed package", but the compression ratio is not comparable to that of RAR.
If you don't need to use 7zip because it is slow, you can consider using solid state by default, and the speed will come up.
"7-Zip still does not support deleting files in the compressed package", no matter WINRAR or 7-Zip, It is not supported when solid state is used. It is supported when non-solid state is used. Because 7-Zip right-click compression defaults to solid state, winrar defaults to non-solid state, so you have such a conclusion.
Some netizens said that it is best to compress a large number of files in the solid state of 7-Zip, such as jpg format, and it will be very slow before and after 60%.

The file format supports Unicode.: 7z (and rar) has a common advantage over zip: Unicode file names are supported.
