Tips for improving the compression ratio, how to achieve a high compression ratio for compressed fil

But don't delete it directly.

There are several ways to compress a file to achieve a high compression ratio:

1. First of all, we right-click on the file we need to compress and select "Add to Compressed File".

2. Since we are compressing the file, if we choose the file format as. rar, generally speaking, the compression ratio of files compressed in this way is higher. If we choose.

zip file format, then the compression ratio is generally relatively small, so I recommend you to choose it as. rar.

3. Next, what we need to do is to check the two options of "Create a solid compressed file" and "Test compressed file", so that the compressed file will be relatively small, you can look at the compression ratio in your file properties, if the file is large, it will be obvious. I hope you tick "Test Compressed File" as we may encounter some unknown errors during the process of compressing the file.

4. Next, we can click "OK", and the software will automatically compress the operation, and then look at the compression ratio of our file.

5. If the size of the file we need to compress is very large, then in order to save time, we can generally choose the file format as. zip, after all, this can save a lot of time.

This depends on what file you are compressing;

If it is a document file, you can basically have a good compression ratio by using standard compression;

If it's some jpg, png and the like, it won't be much compressed!

Also, the compression ratio can be set by yourself.

However, the compression time is longer, and the decompression time is longer than the standard compression method.

1.Secondary compression has little effect.

2.Maximum compression can be achieved with 7-zip.

Extreme compression, compression method bzip2 Dictionary size: 900k Word size not: Assigned Solid data size: solid.

This compression ratio is maximum. But it's not very practical because it takes too much time.

There's no need for that, you're so time-consuming and labor-intensive. And if you try it, the end result is pretty much the same.

And, ah, generally"Extreme compression"The size of the dictionary will not be less than 64m

Less than 64m is very time-consuming. It's always going to be a little more efficient.

It takes a whole day to compress a piece of software, doesn't it make people laugh to death, does it?

The compression rate of this thing is so high that it is out of the spectrum.

Common Format Sorting:

rar=rar4>zip>7z>tar>gz>bandzip>fp8

Ways to speed up compression:

1. Drag and drop the mouse to reduce the operation cost.

The mouse is one of the parts that we use the most in our computer. Drag and drop with the mouse, you can easily complete a lot of work with a simple drag-and-drop. The latest version supports the directory tree file browsing interface to drag and drop each other, and easily realize the compression and decompression of files.

2. Multiple compression configurations, choose the most appropriate compression method.

Good pressure provides storage, fastest, fast, standard, better, best 6 compression methods, users can also configure the algorithm by themselves to achieve the most ideal compression effect. In addition, users can also perform volume compression, make self-extracting files, and set automatic shutdown after compression.

3. Turn on intelligent filtering to improve the compression speed.

The new version of Haowei has better management of high-speed compression, the original compressed file filter list, intelligent processing of files with low compression ratio, and comprehensive guarantee of high-speed function;

The good press should be similar to winrar, which is right-clicked to add to the compressed file. Then select "Fastest" in the compression method, and the good pressure should be about the same.
