7 Zip is a tool whose main function is the compression and decompression of files, like other similar tools such as WinRAR or WinZip does. This time, we will show you how you can compress any file you have on your computer.

Steps to compress a file with 7-Zip

When it comes to a file compression, it’s about the creation of a package, that thanks to a compression algorithm, it is actually based on the reduction of the data to handle, it minimizes the weight or the size of this archive.

To make a file compressed with 7-Zip, first we must do the selection of files or directories that we want to compress, because it’s important to select the corresponding path. With the mouse left button, you need to drag it untill you select all the archives that you want to compress, the selection will make all the files turn blue, then all you have to do is click on the button “ADD” with the plus sing that’s located in the toolbar.

Once we do that, a menu will be opened and there we can form the various parameters on the compression that our file will have.

7-Zip

1-. File: In this option we will indicate the name and location of the compressed file. If we press in “…” it will be possible to determine the location in the graphical way.

2-. File format: In this section the compression format will be resolved, you can choose between 7Z, tar and ZIP. This is then a factor of great importance, according to the format that is used for compression will offer other features.

3-. Compression level: In the compression level of it will determine the compression index that will have the contained files, it will be possible to be chosen in medium out more quickly, a faster, normal, maximum, extreme compression, the higher the compression level of the file, the smaller the file size will be. So it will take up less space, but the time it will take to do the compression will be longer.

4-. Type of compression: This option will determine the algorithm that is used for the compression of the files and will also include the compression ratio of the file.

5-. The size of the dictionary: The dictionary is a very important area of ??memory that is used by the compression algorithm. Increasing the size of the dictionary will increase the compression ratio, delay the same and increase the memory requirements.

6-. The size of the word: This option indicates the size in the pieces of the strings of the characters that will be used by the algorithm so that they do the compression.

7-Zip

7-. The size of the compact block: This option will indicate the size in the pieces of the blocks that will compose the compressed file, while it is larger, the files will be more compressed, but at the same time the greater the risk of corruption.

7-Zip

8-. CPU Thread Numbers: This option will serve to assign to the different threads of the multithreading processors the task of decompression or compression, so that it significantly reduces the time of the task.

7-Zip

9-. Memory Indicators: This option indicates the amount of RAM memory that will be used for both, compression and decompression. The size or type of the compression will depend on some factors like these.

7-Zip

10-. To start in fragments: This option will allow us to divide the file into several parts of a certain size so that we can store it in different media or accommodations, where otherwise, it would not be possible.

7-Zip

11-. Updates: It will allow us to choose among the different ways of a file update in case there is a modification in this.

7-Zip

12-. Options: It will allow us to make the selection of two options that may affect the mechanism of decompression, you can select only one or both.

7-Zip

Once we have chosen all the compression qualities we must press OK to start with the process and once completed, we will find all the compressed files in the location we have selected.

7-Zip

We must consider that the tool comes with the pre-selected options that are indicated for the type of file that we have selected for compression. In any case, if you don’t know which one to choose, our recommendation is to follow the standard options the tool has selected for you and in this way we will avoid any error or loss of our files.
