■Compress the best WinRAR

WinRAR can be regarded as the best compression software. Its performance is much higher than that of powerful software such as WinZip. It should be everyone's choice without hesitation.

WinRAR features include powerful compression, multi-volume operation, encryption technology, self-releasing module, easy backup, etc.

Unlike many compression tools, WinRAR follows the management method of programs under DOS. When compressing files, you do not need to create a compressed package in advance and then add files to it. Instead, you can create it directly. In addition, you can put a It is very easy to add the software to an existing compressed package, making it very convenient to use.

WinRAR also uses a unique multimedia compression algorithm and fastening compression method, which specifically improves its compression rate. Its default compression format is RAR, which has a compression rate higher than The ZIP format is 10% to 30% higher, and it also supports ZIP, ARJ, CAB, LZH, ACE, TAR, GZ, UUE, BZ2, and JAR type compressed files.

WinRAR is a very practical compression tool. Let’s take its latest 2.9 Chinese version as an example to briefly introduce how to use it.

Installation and Settings

After downloading WinRAR, run the installation file and press "NEXT" to install WinRAR into the specified folder.

After installation, the program will pop up a settings window. In order to give full play to its excellent performance, we must first make relevant settings for the software before using it. The "WinRAR File Association" item in this window provides settings for the compression package type that can be associated with files created by WinRAR. Here you can set A choice needs to be made.

In the "Interface Settings" item, check the "Put WinRAR on the Desktop", "Put WinRAR on the Start Menu" and "Create WinRAR Program Group" options as needed.

And in the "Shell Integrated Settings" item below, set up the system mouse right-click menu to add WinRAR commands. It is recommended to select them all, and then click "OK" to complete the settings.

Basic use

1. Compress files

Since WinRAR is a compression software, the author first talks about how to use it to compress files.

Because WinRAR supports the mouse right-click shortcut menu function.

So under normal circumstances, when we compress files, we only need to right-click the file or folder to be compressed in the resource manager. In the pop-up shortcut menu, WinRAR provides "Add To the archive file (A)... and "Add to ×××.rar" two compression methods

Select the "Add to ×××.rar" command, WinRAR can quickly. Create a RAR archive of the file to be compressed in the current directory.

If you want to perform some complex settings on the compressed file (such as volume compression, encryption of compressed files, backup of compressed files, and compression). Add comments to the file, etc.).

We can select the "Add to Archive File (A)..." command in the right-click menu, and in the "Archive File Name and Parameters" dialog box that pops up (Figure 2) WinRAR*** provides five options: "General, Advanced, File, Backup, Comment"

Enter the name of a compressed file in the "General" tab, and the default extension is ". *.rar" and select the archive file type. This program provides two types: RAR and ZIP. The default is RAR type.

At the same time, you can adjust the "Update Method" and "Archive Options" as needed. related settings.

Under the "Advanced" tab, we can use the "Set Password" button to encrypt the compressed file, which can protect the compressed file.

Appropriate selection of "compression method" can improve your compression time. For example, if the compression rate is not very high, it can be "fastest", etc. As for "Compressed volume size", it is also an important option. I once sent a piece of software to a friend by e-mail. As we all know, the free mailbox size is generally 3MB, so I entered "3" in "Compressed volume size". ,000,000" and click "OK".

In this way, a large software is automatically divided into multiple files. Then, the author sent them to the other party one by one, and the other party put all the files in a directory, and restored the software by decompressing the first file.

In the "File" tab, WinRAR provides the function of adding and deleting files. Through this function, we can add files to the compressed package and delete a useless file in the compressed package in time. In the "Backup" tab, we can back up the files in the compressed package in time through various options. In the "Comments" item, we can add relevant comments to the compressed file for later verification.

2. Decompress the package file

For decompression, WinRAR also provides a simple method: in the system explorer, use the right mouse button to click the compressed package file, and then right-click on the system The menu includes three WinRAR decompression commands, among which "Release files to..." can customize the path and file name where the decompressed files are stored.

"Release files here" is the simplest way, which means to expand the files in the compressed package to the current path. "Release files to XXX\" means to create a file with the same name as the compressed package under the current path. folder, and then expand the compressed package file to this path. It can be seen that no matter which one is used, it is very convenient.

WinRAR can also call the WinRAR program to decompress by double-clicking the RAR compressed file. The program interface provides:

Extract to the current folder, preview the document, and test Compress documents, delete documents, add comments to compressed documents, protect the current compressed document, generate self-extracting files, change file paths, and more.

Here we only need to select the document, then right-click to select the required function, which is very convenient.

When decompressing some files in a compressed package, the following method can be used: Select the file or folder to be decompressed in the WinRAR interface.

If you want to decompress multiple files or folders at one time, you can use "Ctrl left mouse button" to select discontinuous objects, or use "Shift left mouse button" to select consecutive multiple objects. Select, then drag it directly to the resource manager with the left mouse button, or right-click the selected file and select the corresponding release directory.

3. Make a self-extracting file

If we want to use WinRAR to make a self-extracting file for a compressed file, we can select the file in the main interface of the program and click on the toolbar Select the "Self-release Format" button (you can also use the shortcut key "Alt That’s it, no need to call WinRAR to decompress it.

In addition, WinRAR also provides functions such as generating volume self-extracting files, converting compression formats, etc., and it is also very simple to use.
