7-Zip is a tool that basically serves us for compression and decompression of files. This is a tool very similar to WinRar or WinZip, with the main difference that it is completely free with all your options and for all the time you require.
However, like most of the tools, this also has some options that surely many of the users that use it don’t know about. 7-Zip gives you everything you need for other tools in one. We have brought a selection of functions that you probably don’t know, these will help you solve all your problems with a file.
Functions that you probably don’t know about 7-Zip
These functions that we will show you below are available in all versions of 7-Zip and will allow you to make any modification to your file.
– View the inside of an executable or a disk image
7 Zip is able to open almost any compressed file, in any format and this includes executables. Although the content is usually not very easy to see, because the vast majority of these files are code, but if you look through the folders you can find some manuals, help documents, icons or images, you just need a little practice to know what what are you looking for.
To access the inside of an executable you must follow these steps:
1-. You should start by opening the tool on your computer. If you have not installed it yet, we recommend that you do it from the official website.
2-. Then you must look for the folder you want to see, you must right click on the mouse and this will open a sub-menu. Once there you must select the Open Inside option or the combination of letters CTRL + PgDwn.
– To test the performance of your computer
7z will also help you test the performance of your computer. You will find in the Tools section the test option or benchmark, this has the main function to know at what speed it is able to compress and decompress a file. This indirectly will give you an idea of ??the performance of the equipment as such.
– Obtain the check sum (CRC) of any file
One of the most unknown functions of the 7-Zip tool is that it gives us the opportunity to know the CRC, SHA-1 and SHA-256 code of any of our files that are in our computer. These numbers are very useful if you share files over the Internet and you want to see that they have been properly downloaded and that there is not a corrupt byte.
To finish with the functions that you may not know about 7 Zip, this is a tool that gives you the possibility to comment on the files, this is something that by default you can’t achieve with the Windows File Explorer.
From the tool 7-Zip you can see the comments already created and not visible with another browser and CTRL + Z opened a window for you to add comments that you can edit later to it.
These are the functions unknown to many people of the 7-Zip tool, with a little practice and following our recommendations, you can achieve any of them. Remember that this is also an excellent tool for file compression and decompression, all you have to do is see the tutorials that we have left on our web side so you know what are the steps to achieve any of your tasks with this application.
In addition, one of the functions offered by 7-Zip is the ability to unify and split the large compressed files to send them by email or upload them to a web page or the cloud.
You should bear in mind that none of the processes performed by 7-Zip are completely permanent, because this tool will always keep the original of the file, this means that basically it will create a copy of the file, compressed or unzipped, in the location that you have previously chosen. For the process, this will allow you to have total control of your files and the content of it, you can also protect them with a password to prevent other people from knowing the content of your archives.
7-Zip is an excellent tool for compression and decompression of files, often compared to WinZip or WinRar, but the main benefit of 7Zip is that it is a completely free tool that provides very good options for users.
This time we want to describe step by step how you can unify the divided files with 7-Zip. Splitting a large file, such as a movie or a program, into smaller pieces is very useful to be able to send it by email and upload them to a cloud service web site, burn them to a CD, DVD or flash drive, this is very useful because not always with compressing it we can reduce its size enough to make the aforementioned options.
Before starting we must remind you that to unify the divided files you will have to install the program on your computer and you must download it from the official web site of the tool so that you are completely sure that this is the best version of the program.
How to unify split files with 7-Zip
1-. The first thing you should do is open the program, if it’s in a folder and you have not executed it yet, you should do it.
2-. Once you have opened the program you should look at the computer and locate the place where the files that are divided and that we want to join are located. We must bear in mind that all the pieces of the file must be in the same folder, otherwise unification can not be done.
3-. We must select the file that among those we want to unify have the lowest number, then we must click on it once more and you must select in the tool bar the icon of the same and you must press “Extract“.
4-. By doing this action we will open a window where we will be indicated the name that we will assign to the unification. Normally you are left with the same name you already have and we can also choose the location of our computer where the file will be created and complete and joined after completing the process.
In case you want to change the location, you must open the tool’s browser, this is achieved by clicking on the three points that we see at the end of the bar where the file location is indicated, once you press it you can select the location that you want to save it.
Once you are satisfied with the name of the file and the location where you will find it on your computer, you must press OK.
5-. A window that will open after pressing OK will show us the process of extracting the files, as is logical, the more pieces there are and the larger the size of them, the longer the conversion will take. We must let the tool finish the process taking care that the equipment does not turn off or that we press cancel by mistake.
6-. Once the process is finished, we will see a new folder with the name of the file that we have assigned, if we enter it, we will find our file perfectly united and that can be opened perfectly with the program that we have thought for it.
In addition, you will keep the files archived, in case you wish to share them on the web. In case you are not going to use them again, once you have verified that the unification went perfectly, you will be able to eliminate them from the computer and save a little memory and space in it.
As you can see, 7-Zip is a very versatile tool that gives us options that other tools ask us to pay for them, this makes it completely free and without problems of any kind. Our main recommendation is that you follow carefully the steps that we have given you previously, this way you will not have problems with the unification of your files, in the same way once you have finished the process check if the file is well unified. Don’t erase the originals without first doing this.
Pay attention to all the parties you’re unifying, avoiding mistakes so as not to waste time in the process. Remember that this may take a few minutes and you should be patient because it is not a process that can be accelerated.
As you probably already know very well, 7 Zip is an excellent application for compression and decompression of files, this is even at the same level as tools like WinZip and WinRar that fulfill the same function with the difference that 7-Zip is completely free in all the options it offers.
This time, we want to talk to you about a use that not many people know can be achieved with this tool and that is very important for sending large files such as movies or a program, we are talking about split files.
Splitting a large file like the ones mentioned above, in smaller ones, is very useful for you to send by email, you can upload them to a free web page or save them on a pendrive without too many problems. Not always when we compress a file we reduce its size enough to be able to do all the actions listed above.
How to split files with 7-Zip
Before starting we must remind you that this is a tool that you should download, preferably from the official website of the service, and that we must install on our computer, this is a tool that doesn’t require too much space on your computer and that you can install without many problems in any language you want.
Now let’s start with the split files with 7-Zip
1-. The first thing you should do is open the program on our computer. If you have not executed it yet, you must open the folder that contains it and do it.
2-. Once this is done and inside the tool as such, you should look for the file that we want to start.
3-. Once we have located it you will have to select the file that we want to leave, click on it once and then in the toolbar you will have to press on the option of “Add”, this is represented by a sing + of green color.
4-. Once we press the “Add” button, it will show us a window where it will indicate the name that we want to assign to the partitions and the place where we want to create the compressed copy of this file.
If we want to vary the folder, you must open the browser, this you will do by clicking on the three points that we see at the end of the bar where we see the location of the file.
To split the file into several pieces, you must go to the end of the window just in the section that tells us to Split to Volumes, Bytes. Once located, you must display the arrow and if any of the predefined options serve us we must choose it, otherwise, write the size that we want each of the pieces of our file.
Once we have set the value we want, we must click on the OK button and the process will begin.
5-. When we press the OK button, the compression process will begin and at the same time the file will be split in the size indicated in the SPLIT section. We must wait for the process to finish, keep in mind that this is a process that may take time depending on the weight of the partitions and the file in general.
6- Once the process is finished, we can go to the folder where we have indicated the tool that will keep the partitions of our file, there you can see that next to the original file, we have two new files, these will have the same name, but they will be different with a number at the end, these are the files that we have split.
Once checked that the files are in perfect condition, if you think you will not need the original file anymore, you can remove it from the computer in its entirety and in this way save a little memory space.
And done, it’s that simple to split a heavy file with 7-Zip, remember that this isn’t only excellent to save a little space, but now you can send it to whoever you want without any problem. Keep in mind that you can place a password protection to the files you are splitting, this will give you the assurance that not anyone can see the content of them.
7-Zip is one of the most complete tools to compress and decompress files, this is a tool very similar to WinZip or WinRar, but has an advantage that the others don’t have, all the options offered by 7 Zip are completely free and unlimited, so you will not have to pay a monthly fee to use it or be against the clock all the time.
7-Zip has two basic tools, compression and decompression of any file in almost any format that exists, but also has other advantages such as putting a password to compressed files.
If you are looking for a simple, fast and secure way to put to your compressed files a password so you can share them without any fear on the web, we have created a tutorial so you can place it for any file you want, thanks to the tool offered by 7-Zip.
How to put a password to a compressed file
Put a password to a compressed file can be very useful if we want to protect or limit access to it, because only those people who have a correct password can access the content of it.
To place a password to our files with 7z, we must start by following the instructions that we will show you below.
1-. The first thing you should do is open the 7-Zip program and you will have to click on the folder that contains the content that we want to protect with a password.
2-. Once this is done, we must look at where on our computer is the file that we want to place a password.
4-. Once selected the compressed file to which we want to place the security password, you must click on the file to select it and then in the toolbar you must locate the icon + “Add“, this is the first of the buttons and is a + sign in green.
5-. Once this is done, it will show us a window where the name that will be assigned and the place of our team where we want the copy of the compressed file will be indicated. If you want to change the location of the folder, you must open the browser by clicking on the line of three points that we see at the end of the bar where we read the location of the file.
6- In that window we see all the options that 7-Zip has at our disposal to put a password to our document. In that same window you will see the option to place the password to our file. This area you will see under the name “Encryption” and you will see the two boxes where we will place the password we want, in the first of them you will have to write the password and in the second repeat it.
If you fear putting it wrong, you can press on the option that allows us to show the password while we assign it and once we have been satisfied with the password we have placed, you must press the OK button. This will start immediately with the compression of the file and the placement of the password, in this case all we have to do is wait for the tool to finish the process, this may take some time depending on the size of the file and the other options that we have configured for the compression of it.
Once you have finished the process, you can see that you already have a new compressed file, with the contents of the original file or folder and you will also be protected with a password. We recommend that you write down the password somewhere to avoid forgetting it, if this happens there is no way to go back and you will have to start over.
If you are done with the compression process and you have written down the password in a safe place, you will be able to remove the original file from the computer, this will free up a bit of memory and give you full security that your information is safe.
When you decide to unzip the file, the password will be requested, if we don’t introduce it or we do it incorrectly, you will not be able to access the information. And it’s done, it’s as simple as you can have all your compressed files with a password, this is ideal for people who handle sensitive or very important information and to send information through internet services, the cloud or by email.
This time we want to show you how you can unzip a file with 7-Zip. As we have already told you, this is a completely free program that allows us to do the basic compression and decompression of any file that we have in our computer. This tool is able to compress and decompress different formats, which is an excellent help for people who handle heavy files on their computers.
If you use a computer every day, it is possible that at some time you have the need to compress or decompress a file. It may be to reduce the size of a document and with this to send it by email or on the contrary, you must extract the contents of a compressed file that you have downloaded from the internet or that you have received via email.
For this task you can find many programs and it is true that one of the best are WinZip and WinRar, but 7 Zip is positioned as one of the best too, because, in addition to being completely free in all its options, it offers a solution to anything we need to do with the files on our computer.
How to unzip a file with 7-Zip
We start with the most reasonable step, you must download the program on your computer. You can find it on different web pages, but we recommend that you download it from its official website, this way you are sure that it is the latest version and the best version for your computer.
This is a program that is available for all operating systems and also for all versions of computers, so you will have no problem finding the ideal one for you.
The installation of the program is very simple, all you have to do is follow the instructions that will be indicated by the installation assistant and that’s it. Keep in mind that this is a program that offers a wide variety of languages, so we recommend that you choose the one that best suits you.
To start unzipping a file, the first thing you should do is look for the file you want to compress in your computer, it must have the .ZIP or .RAR formats.
Then you must press the right mouse button on the file you want to unzip, this will open a sub-menu where you can see some options of your file. If you have the 7-Zip application installed, it will appear in the options to unzip the file.
Once the 7-Zip option is located in the sub-menu, a second sub-menu will open where it will indicate the options you can do with the 7-Zip tool and the compressed file that you have on your computer and that you want to see what is inside.
You can click on three options that 7-Zip allows you, this is something very particular about the tool, because it will allow you to make the decision of how you want to open the compressed file of your computer. Among the options to choose from, you will find the following:
This is the option that will allow you to select the folder where the files will be saved, once they have gone through the decompression process.
In this option we will be able to decompress the file in the same folder where the file is currently, in the case of the download folder, there will be the content that we will unpack if we use this option.
This option will create a folder with the name of the compressed file and decompress the file in it.
Once you select one of the options, in our case we will select the “extract in” option which will create a folder with the compressed files with the same name as the compressed folder.
You will see that a folder with the same name has been created, only that this time it is not compressed and you will be able to see and use any of the files that are inside it and that’s it. It’s as simple as you can unzip a file with the 7-Zip tool.
Keep in mind that if the file has a password you will probably need to enter it before decompressing the folder, it must be given by the person who sent you the compressed file or the website where you downloaded the file. If you do not have this password, it is likely that you will not be able to decompress the file.
