Unzip the *.xz archives under Windows. File extension XZ $ unzip archive options

Most people already know about the compression/decompression utility xz. I don’t know yet. So I wrote this informative topic.

Xz - compressed data format, like gzip, bzip2, which is upgraded to GNU add-ons.
Vikorist's LZMA algorithm, the same one found in 7z, means that it is possible to more strongly compress many types of data, such as text, binary data has not yet been compressed into equal and standard ones.
xz is being vilified in the new rpm 4.7.2 for compressing archives.cpio in rpm packages (victorized on Fedora 12).
In ArchLinux, .tar.xz is used as a package.
GNU tar now has the -J --lzma option, which plays the same role as -z for gzip, -j for bzip2

Pros:
High level of compression

Disadvantages:
great combination of resources:
cpu time
memory (adjusted, but still more, lower gzip, bzip2).
Zocrema xz at --best aka -9 living up to 700mb! with compression and 90MB with decompression

Features:
The regeneration of the great memory is interspersed with the forward calculation of available resources.
Integration into GNU tar
robot with threads
optional: progresbar via -verbose

I don’t want to overshadow this important topic with graphs and others, but we can’t do without them:
Having earned a banal race gzip, bzip2, xz, this is a step of constraint, accommodating the hour. Also, as a guest, take the part of WinRar (whether drunk or under wine, but still showing excellent results)

We subtract 4 squares:
Lower left - high and low: gzip and winrar fastest.
Upper left: victorious spivvidnoshenya constraint/hour: shows itself a little better bzip2, xz on 1 and 2nd level of constraint, that
Upper right: operating pressure mechanism: long or even squeezing xz
At the bottom right: there is no one, and who needs a long-time worker and an archiver that squeezes weakly?

But the coordinate grid was not selected: how do we estimate the hour? categories! for example, a quick one - 10-20 seconds, an average from half to half, more than 2 times - a long time.
so the logarithmic scale is more accurate here:

And how to evaluate them as a constraint on the flow, on my Core2Duo E6750 @ 2.66GHz,
then Viyshov has such an axis graph:


tobto. Vikoristuyuchi yak compression of the conveyor gzip -1 or gzip -4, in a 100Mbit network you can drive up to 25MB/sec of uncompressed data. (I've checked it several times - gzip -4 seems to give a greater profit from -3 to -5)
cat /some/data | gzip-1c | ssh user@somehost -c "gzip -dc > /some/data"
xz you can vikorist in such a channel on channels<8мбит,

Obvious visnovok (For spriyannya K.O.)

P.S. As if I didn’t bother with xz, the reasonableness of the spent money was WinRar Wins.

For obvious reasons, it is installed on the computer antivirus programs possible, perhaps scan all files onto your computer, as well as every file on your computer. You can scan any file by right-clicking on the file and selecting the appropriate option to scan the file for viruses.

For example, on this little baby you can see file my-file.xz, then you need to right-click on this file, and select the option in the file menu "Go get help AVG". When you select this option, AVG Antivirus will open, which will scan the file for viruses.

Sometimes the decision may be canceled as a result incorrect software installation What could be related to the problem that occurred during the installation process? This can affect your operating system Link the XZ file to the correct application software, falling into such a title "file extension association".

Sometimes it's simple reinstalling 7-Zip We can solve your problem by correctly linking XZ with 7-Zip. In other cases, problems with file associations may arise as a result filthy programming software security a retailer, and you may need to contact a retailer to obtain additional assistance.

Porada: Try updating 7-Zip to the latest version to re-download so that the remaining fixes and updates are installed.

This may seem obvious, but often The XZ file itself could be causing the problem. If you have received a file through an email attachment or have downloaded it from a website, and the process of downloading has been interrupted (for example, a connection to life or for other reasons), the file may be corrupted. If possible, try making a new copy of the XZ file and try opening it again.

Carefully: A corrupted file can be caused by additional bugs from previous or existing programs on your PC, so it is important that you keep up to date with antivirus updates on your computer.

What is your file XZ related to hardware security on your computer, to open the file you may need update device drivers, related to these possessions.

Qia problem Depend on the types of multimedia files, which lies under the successful release of hardware security in the middle of the computer, for example, sound card or video card. For example, if you are trying to open an audio file but cannot open it, you may need to Update sound card drivers.

Porada: If you try to open the XZ file, you will be deleted notification about the cancellation, linked to the .SYS file, problem, it is clear that you can associated with faulty or outdated device drivers, what needs to be updated. This process can be made easier with the help of software for updating drivers, such as DriverDoc.

The Crocs didn't see the problem, and you are still having problems with the XZ file permissions, which may be related to the number of available system resources. Some versions of XZ files may require significant amounts of resources (eg memory/RAM, processing power) to run properly on your computer. This problem occurs often when you try to use old computer hardware and a new operating system at the same time.

This problem may arise if the computer needs to return from work, and parts of the operating system (and other services that run in the background) may You need to have a lot of resources to open the XZ file. Try closing all programs on your PC, first opening XZ Compressed Archive. By making the most of all available resources on your computer, you will have the best minds to try opening the XZ file.

Yakshcho vi vikonali all descriptions more details, and your XZ file, as before, does not open, you may need to log out renovation of equipment. In most cases, probably with older versions of the device, the calculation intensity may be less than sufficient for most of the customer's benefits (as you do not rely on a richly resource-intensive robotic process sora, such as 3D rendering, financial/scientific modeling or intensive multimedia robot). In such a manner It is absolutely certain that your computer does not run out of unnecessary memory.(often called “RAM” or random access memory) is the file storage name.

As for the interface, the Chinese retailers did a good job here. They didn’t just copy the design and functionality from the Winrar archiver, but add...

WinRAR is a private program designed for working with archives. The utility includes a wide range of options. WinRAR compresses data better than its competitors, saving disk space and usage time. Supports a variety of archive formats and is suitable for compressing multimedia files. Automatic recognition of the file format, a special algorithm for compressing data and an optimal packaging method - program advantages. WinRAR can compress executive, multimedia files and libraries of object modules. The add-on allows you to divide archives into separate volumes and save them on different storage devices.

Ashampoo ZIP is an archiver program that helps you compress and save the necessary information. It works with transparent formats, allowing freelancers to edit voluminous documents in a simple manner. Ashampoo ZIP has a wide range of different functions. With additional programs you can create, unpack and distribute archives. In addition, the program supports reading, updating, encryption, and also migrating conversion. List of formats supported by Ashampoo ZIP. In addition to creating archives, the program supports unpacking documents in more than 30 different archival formats.

Unfortunately, to increase the availability of computer workers, distributors of various computer software are releasing simple, manual and clear programs that can really help the robot. One of these programs is a new development of the WinArc archiver. This utility is available for casual editing and will help you not to archive or unzip any file that you want to download. This utility, during its operation, vikoristas all processor cores, thereby speeding up the archiving process. In addition to this, there is the function of regulating the VKR, which can significantly reduce the impact on your equipment.

These days we deal with archive files even more often and on all platforms: Windows, Mac or Linux. These could be programs, backup copies of systems or databases, or simply archives of files. We often have to create our own archives in Linux in order to transfer a few files to friends or upload them to a file sharing service. The archives contain all sorts of software packages, output codes, and a lot of other files that are distributed all over the Internet. It is very important to learn how to archive files in Linux via the terminal, as you may need to do so if you do not have access to the graphical interface, or simply in the future the terminals will become more accepting of processing.

In this instruction, I want to take a closer look at utilities for archiving in Linux, we will look at not only the most popular and universal utility - tar, but also other lesser known ones, as well as popular compression algorithms.

This means that archiving in Linux is not the same as compressing files in Linux. Archiving is the process of combining several small files into one, using the method of manual further transfer, saving, encrypting or compressing. As I already said, archiving is done with special utilities. We don’t like archiving files in a graphical interface, you’ll figure them out yourself; our topic is the terminal.

The most popular archiving utility for Linux is tar. It is also used for archiving outgoing messages and packing packages. For compression, other utilities are used, depending on the compression algorithm, for example, zip, bz, xz, lzma, etc. Archiving starts at first, then it is constrained by other programs. Automatic launch of various compression utilities for a created archive is supported in tar and other similar programs with the help of special options.

Archiving also has the advantage of encryption. Now let’s look at the utilities that help you archive Linux files and how to access them.

Tar

Tar is a standard utility for archiving Linux files. Step by step, with a small archiving program, it turned into a powerful tool that supports work with a wide variety of archive options and compression algorithms. The program supports a large number of parameters. Let's take a look at the syntax and basic parameters:

$tar options f file_to_write /folder_files_for_archive

Now let's look at the main options:

• A- add the file to the archive
• c- create archives for linux
• d- align files in the archive and unpack files from the file system
• j- squeeze archives for help with Bzip
• z- compress archives using Gzip for help
• r- add files to the end of the archive
• t- show instead of archive
• u- update archives to the file system
• x- Remove files from archive
• v- show report information about the work process
• f- file for recording in the archive
• -C- Unpack the specified folder
• --strip-components- add n subfolders

Now let's take a look at archiving files on Linux. To create archives, use the following command:

tar -cvf archive.tar.gz /path/to/files

To unzip the tar linux archives:

tar -xvf archive.tar.gz

It’s really easy to remember the option for packaging. c - C reate, and for unpacking - x-e X tract.

Compressed archives are created this way, only with the -z option, unless you use gizp encryption, if you need bzip, then the -j option is disabled:

tar -zcvf archive.tar.gz /path/to/files

$ tar -zxvf archive.tar.gz

For example, let's look at how to archive a folder in Linux:

tar -zcvf home.tar.gz ~/

Although we can do it differently, we can remove the same archive by first creating the original archive using tar, and then compressing it with a compression utility, but here we take away more control over the compression process:

gzip archive.tar

You can also clean up the squeeze:

gunzip archive.tar.gz

The utilities summarized below are discussed below.

To add the file to the archive, vikorist:

tar -rvf archive.tar file.txt

To download one file, the syntax is the same:

tar -xvf archive.tar file.txt

You can select a number of files behind the identity template using the additional wildcard parameter, for example, all php files are included:

tar -xvf archive.tar --wildcards "*.php"

To unzip tar linux archives, you can use the same folder with the archive name to unzip to the desired folder using the additional -C key:

tar -xvf archive.tar -C /path/to/dir

We've looked at the standard utility, now let's briefly look at its alternative. There are not so many of them, and most of them are already outdated.

Shar

Shar allows you to create archives that unpack themselves. Essentially, this is a shell script, and to unpack it you need a Bash shell or anything else from the Bourne Shell. Shar has one advantage, but it is also potentially unsafe, since the archive is a file that is saved.

Shar options:

• -o- save archives to file instead of standard output
• -l- Limit the size of the output file
• -L- limit the size of the output file and split it into parts
• -n- The archive name will not be included before the header
• -a- allow automatic generation of headings

Use shar to archive the linux folder:

Creating shar archives:

shar file_name.extension > filename.shar

Unpacking shar archives:

Ar

ar is a utility for creating and managing archives. It is mainly used for archiving static libraries, but it can also be used for creating any kind of archives. Previously, it was used frequently, but it was used by the tar utility. The virus is only used to create and update static library files.

• -d- Visibility of modules from the archive
• -m- moving members to the archive
• - p- assign specific members to the archive
• -q- shvidke dodavannya
• -r- add a member to the archive
• -s- Create an index to the archive
• -a- add a new file to the existing archive

Next, let’s look at the butt of the vikoristan. Let's create the static library libmath.a from the object files substraction.o and division.o:

ar cr libmath.a substraction.o division.o

Now let's extract the files from the archive:

In this manner, you can unpack a static library.

Cpio

cpio - means Copy in and out. This is another standard archiver for Linux. Actively researched in the Red Hat package manager, as well as for creating initramfs. Linux archiving for primary files does not interfere with additional programs.

Utility options:

• -a- reduce the download time to files after copying
• -A- add file
• -d- create catalogs for consumption

Vikoristan's butt. Creating cpio archives:

file1.o file2.o file3.o

ls | cpio -ov > /path/to/output_folder/obj.cpio

Unpacking archives:

cpio-idv< /path/to folder/obj.cpio

The archive of the linux folder is also saved.

Archive compression on Linux

We looked at how to create archives on Linux. Now let's talk about compression. As I said, for the sake of constraint, special utilities are used. Let's take a brief look at a few of them

Gzip

The most commonly used method is Gzip. This is a standard Unix/Linux compression utility. For decompression, use gunzip or gzip -d. Let's take a look at the syntax:

$ gzip options file

$gunzip options file

Now let's look at the options:

• -c- display archives from standard versions
• -d- Rozpakuvati
• -f- Primusovo unpack and squeeze
• -l- show information about archives
• -r- recursively iterate through directories
• -0 - minimal pressure
• -9 - maximum rhubarb compression

Please see the application in the description of the tar utility. For example, we will compress the file:

gzip -c file > archive.gz

And now let's unpack:

gunzip -c archive.gz

To compress a folder in Linux, you will first have to archive it using tar, and then compress the file to the archive using gzip.

Bzip

bzip2 is another alternative compression utility for Linux. It's more effective than gzip, but it works better. To unzip, use the bunzip2 utility.

I won’t describe the parameters of bzip2, they are similar to gzip. To create archives on Linux, vikorize:

The online catalog will create a file file.bz2

Lzma

New and highly efficient compression algorithm. The syntax and options are also similar to Gzip. To unpack, use unlzma.

Xz

Another highly efficient compression algorithm. Back crazy with Lzma. The wiklik parameters are also similar to Gzip.

Zip

Cross-platform utility for creating archives in zip format. I am familiar with Windows implementations of this algorithm. Zip archives are often used for exchanging files on the Internet. Using this utility, you can compress files, or compress the linux folder.

Utility syntax:

$zip options files

$ unzip archive options

Utility options:

• -d delete a file from the archive
• -r- recursively minify directories
• -0 - Archive only, without pressure
• -9 - the highest degree of compression
• -F- vipraviti zip file
• -e- Encrypt files

To create Zip archives on Linux, vikorist.

We hope that we have helped you solve the problem with the XZ file. If you don’t know where you can download a program from our list, click on the message (these are called programs) - You will find information about the place where you can download a safe installation version. noi programm.

This page can help you with information specifically on this or similar foods:

• How to convert an XZ file to another format?
• What are the extensions to the XZ file format?
• What programs serve XZ files?

After reviewing the materials on this page, you, as before, did not receive satisfactory evidence regarding the supply of food, which means that the information provided here about the XZ file is not correct. Contact us using the contact form and write if you do not know any information.

What else can cause problems?

There may be more reasons why you cannot open the XZ file (not just the number of related programs).
According to Pershe- The XZ file may be incorrectly linked (unusually) due to the installation of an add-on for its maintenance. In this case, you need to change this connection yourself. To do this, click on the right mouse button on the XZ file that needs to be edited, click on the option "Help with help" and then select from the list the program you installed. After such problems, the XZ file will continue to have problems.
In a different way- the file you want to open may just be damaged. This time you will best be able to find a new version of it, or download it again from the same device (it is possible that the drive in the previous session has not finished downloading the XZ file and it cannot be opened correctly).
