archiver program, appeared in that distant time when the amount of free space on the hard drives were estimated total tens or hundreds of megabytes, lasted to the present time, having undergone only evolutionary development.This demonstrates the relevance of data compression technology.In light of this fact, every computer user has to understand very well how to unzip the file, otherwise the response will have to use the search on the Internet, that means the loss of his time.
So, what is an archiver?As is known, all the information on the computer, including files, a digital data, or, more properly, certain combinations of zeros and ones.Their number and total size of the file are in direct proportion.The obvious conclusion that there may be two solutions to optimize information: to increase the capacity of storage devices and to reduce the volume occupied by the data.The first way is quite predictable and is now very widely used: capacity hard drives and flash drives with each year becomes more and more.The second is realized by archiver.In its work, such programs are analyzed compressible (packaged) files for the presence of identical combinations of zeros and ones (pieces of code) and replace the markings found.As a result of this treatment, a decrease in file size can be up to 80%, while removing all of the original data is restored.
Beginners often raises the question of how to unzip the file, because the work itself and its contents should not be.In fact, nothing complicated about it.There are several ways to decompress the file.The most correct - Installing this in the archive utility with which was created archive file.In this way, any problems with unpacking arises.The problem is that now is difficult to determine exactly how the data were processed by the archiver.For example, if so, how to extract a file rar, everything is clear, as is typical for this expansion program Rar, something with wim or tar, is not so simple.The following method is based on the fact that most modern archives are universal and allow you to create and decompress files compressed with alternative software.If the user does not know how to unzip a file, you can try to do any such program.For example, if you want to unzip the file with the extension rar, you need to install WinRAR (system Windows).Run it, we follow to the desired file by placing the cursor in the top menu, click "Remove."Conductor choose a place to decompress.You can also use some additional features (better to leave the default).
avoid problems with unpacking is possible by the installation of two programs: WinRAR and 7-Zip.Register in the system, they will extract the files from the archives of the majority.
The third way is to use unpacking shell Total Commander plug-ins with established archives.Point to the file, press the combination of Ctrl + PgDn (Page Down), Ins key mark the desired files and copy them (F5) into the prepared directory.
If the user wants to answer the question "how to unzip the file iso», then we can again take advantage of the Total Commander.Steps recovery in this case is similar.In addition, you can open ISO-files in the program Ultra ISO or Daemon Tools, and copy the contents of the archive to the desired directory.In the first case suitable technique Drag- & amp; -Drop, while the second will have to insert the ISO virtual drive and copy the files from there, in the same way as with conventional CDs.
