HOW TO USE WINRAR FOR STRONG COMPRESSION

First, you need to install Winrar, then right-click "Add to Compressed File", enter the compressed file name and path in the compressed file name, select the degree of compression in the compression method, and the smaller the file, the longer it will take.

Then select the other options according to your needs and click OK (you have to wait for a while, there will be a progress table displayed).

1.Change the compression method (default is standard) to best.

2.A lot of small files can be used"Solid"

3.For files that are not used, the compression ratio of WinRAR is different.

Like what. files, basically, can't be compressed much;txt file, it's compressed, that's but: quite: big!

The above ** my answer.

4.It can be compressed continuously (the more times, the greater the risk, the light will damage the file, or the heavy will lose the file, and the scale can be controlled by yourself).

5.Audio files use lossy compression, such as changing from two-channel to mono

Compression is not how small you want to press, you can press as small as you want, it depends on what kind of data is pressed, I once compressed some web pages from 60m to 2m, but the volume has hardly changed after *** pressed.

The compressed file is in RAR format, which can be done using WinRAR software.

The steps of the method are as follows:

3. After the installation is completed, right-click the folder to be compressed and select "Add to".rar", wait a few moments to complete the packing and compression of the folder.

4. After the compression is completed, it can be delivered to the folder in the same path, and the folder has been successfully packaged into a rar archive.

Extend. RAR is a proprietary file format for data compression and archiving packaging. The developer, Eugene Roschal, so RAR's full name is:

roshal archive。The first public version of the RAR was released in 1993.

Similarly, RAR files are usually compressed more than zip files, but the compression speed is slower. Because the RAR file header also occupies a certain amount of space, when there is not much room for data compression, the compressed file may be larger than the original file.

One of the main advantages of RAR is that it is possible to split the file compression target into multiple files, and it is easy to extract the source file from such a split compressed file.

In addition, RAR also supports the compression format, which compresses all files into the same data area to increase the compression ratio, at the cost of decompressing a single file and having to decompress all the files in front of it. The encryption algorithm of the new RAR uses AES, while the encryption algorithm of the old RAR is private. Both algorithms are difficult to crack, so they can only be cracked using dictionary brute force without a password.

Redundant repair information can also be added to the RAR, which can be used to repair the archive when the file is corrupted but the repair information is good enough.

RAR files are one of the most commonly used compressed files, which are usually opened and processed with WinRAR software.

What software can open the RAR format?

Select a file that you want to compress, right-click on it, and add it to the compressed file, and you can talk about it.

WinRAR is a very commonly used file compression software, it can compress all kinds of files into a small compressed package, convenient for transfer and storage, WinRAR supports a variety of compression formats, including RAR, ZIP, 7Z, etc., and can also encrypt and protect the archive to ensure the security of the file, using WinRAR to compress files is divided into the following three steps:

1. Right-click on the file you want to compress on your computer, and click the "Add to Compressed File" option in the menu.

2. In the compression file name and parameter window, check the required RAR format, and you can also set the compression file name, compression method and other related parameters as needed.

3. After completing the above operations, the file will be successfully compressed into RAR format.

If you want to directly compress the size of the file itself, we can also use other compression tools, such as Hi Format Compressor.

1. Open Hi Format Compression Master, you can see the five functions of **compression, **compression, PDF compression, word compression and PPT compression, select the required compression function as needed, if you need to compress**, click "**Compress".

<> when you encounter the problem that the file size is too large, you can use Hi Format Compression Master.

For compression operations, the software supports batch compression of files and custom setting of various compression parameters, which can adapt to different needs in various scenarios.

Select the file to be compressed, right-click, and use Winrar's shortcut options in the context menu to compress the file. For details, see the following steps.

1. Find the file you want to compress in the computer folder, and then select the file with your mouse.

2. Then right-click and click the "Add to Compressed File (A)" option in the context menu.

3. Then you will enter the "Compressed File Name and Parameters" interface, you can set the compressed file name, format, save location and other options, after setting, click OK to exit.

4. Then a compression progress box will pop up, just wait for the compression to complete.

5. If you need to compress the file quickly, directly select [Add to] in the right-click menu. Once you have done the above settings, you can compress the file with Winrar.

1. After the first installation is completed, the winrar software will pop up the setting interface, if you are not installing it for the first time, you can also open it by right-clicking on any compressed file, or open the setting interface in the winrar program group.

2. In the menu bar of the settings interface, we click on the "Options" menu and then select the "Settings" button.

3. In the pop-up settings interface, we only need to set the "Path" and "Comprehensive" options.

4. The default temporary extraction file of WinRAR software is stored in the C drive, and after the decompression is completed, these files will be cut to the decompression directory you specify, which may cause you to decompress the file slowly, we can modify the path here, so that it can be directly decompressed to the root directory of the partition where the decompression file is located.

5. Then locate to the "Comprehensive" option, first check "WinRAR Associated Files", you can choose which formats of files need to be opened with WinRAR, it is recommended to select "Select All".

Here's how to do it:

1.Click on the win icon (Start) in the bottom left corner of the desktop, and then click on "All Programs" winrar.

2.After opening Winrar, click on "Options" at the top of the software interface and then click on the "Settings" option in the drop-down menu.

3.Once the software settings window is open, click on the "General" tab above the settings window.

4.Once you are in the General tab, tick the "Cascading Context Menu" option.

5.After checking, click OK, and then close the compression software, and then click the right button again, and there will be a winrar compression option in the right-click menu.

To put it simply, the file that has been manually compressed by the compression software is called a compressed file, and the principle of compression is to compress the binary ** of the file, and reduce the adjacent 0,1**, for example, there is 000000, you can turn it into 6 0 to write 60, to refer to the space of the file.

The basic principle of compressing a file is to find duplicate bytes within a file and create an identical one"Dictionaries"file, and denote it with a **, for example, there are several places in the file with the same word"People's Republic of China"Represented by a ** and written"Dictionaries"files, so that the purpose of shrinking the file can be achieved.
