How does 7-Zip software compress files?

php editor Youzi will introduce you how to use 7-Zip software to compress files. 7-Zip is an open source file compression tool that supports multiple compression formats, such as ZIP, RAR, TAR, etc. With simple operations, you can easily compress files or folders into a compressed package, thereby saving storage space and facilitating file transfer. Next, we will introduce in detail how to use 7-Zip software for file compression on Windows systems.

First of all, we can go to the 7-Zip official Chinese website (sparanoid.com) or the software store to download the 7-Zip software.

After clicking [Add] to pop up the [Add to Compressed Package] dialog box, we can modify the name of the compressed package and set options such as compression format. If we need to protect the compressed file, we can also set password protection.

In addition to opening the software and then compressing it, you can also click on the file that needs to be compressed and compress it through the right-click option of the mouse.

After right-clicking the mouse, in the 7-Zip list, select [Add to compressed package] to compress. After selecting, the above [Add to compressed package] dialog box will pop up.

If you do not need to modify the compressed package name or set a password, you can select [Add to "original file name".7z] or [Add to "original file name".zip] according to the compression format to directly compress the file. Set options; if you want to compress the file and send it directly by email, you can select the option with "And Mail" to compress the file.

If the 7-Zip software cannot be used after installing it, it may be that there is no associated file format when installing the software, and we need to set it manually.

After opening the 7-Zip software, click [Options] in the tab [Tools] list;

In the [Options] dialog box, select the first " " icon at the bottom of the [System] page, and then select the file you want to associate in the list. When the blue "Z" association icon appears on the left side of the file, It means the association is successful. Once associated, the software is ready for use.

It should be reminded that after compressing files through 7-Zip software and setting a password, you must save or remember the password, because if you forget the originally set password, you will not be able to decompress or open the 7Z compressed package. 7- Zip software also does not have a "forgot password" option.

If you really forget it accidentally, you can try to use tools to help us.

For example, the Pepsi Niu ZIP password recovery tool can retrieve lost passwords for compressed files and supports both Zip and 7-Zip format files.

The tool provides 4 retrieval methods. After importing the compressed package into the tool, select one or more of them and follow the prompts.
