Returns whether the stream is currently associated to a file. Streams can be associated to files by a successful call to member open or directly on construction, and disassociated by calling close or on destruction. The file association of a stream is kept by its internal stream buffer: Internally, the function calls rdbuf-isopen Parameters. Decompress tar file into directory.

If you need a quick solution to compress and decompress files, stay with us, and read the following article because we will get you out of doubt about which compressor/decompressor to use according to your needs. But first, a few important notes to understand before downloading any app for decompression and file compression.
What is the main purpose of file compression and decompression?
Any file compressor/decompressor's goal is to make the files that we want to store on our devices or want to share take up much less space. It seems obvious, but this quality is especially useful nowadays for files that we want to store and send through mobile devices with less storage space than laptops or desktops. For this reason, more solutions are emerging that have been developed exclusively for 'mobile'.
In addition to taking up less space on your computers and devices, file compression allows you to share and download files faster and easier.
Finally, it is important to highlight that the programs to compress and decompress files go beyond their basic functionalities, allowing them to:
- compress and decompress in different formats
- protect, manage, and share the files through very diverse systems and platforms
How are Zip files different from Rar files?
Zip and Rar are the most common compression formats, but you should know some differences between them.
- Zipformat: Zips could be said to be more 'universal' than Rares since they can be created, displayed, and/or extracted by almost any decompression program. They are not limited to a single program. As for operating system compatibility, Windows XP, Mac OS X, and some versions of Linux usually have a pre-installed program to open Zip files.
- Rar format: Rars comes more limitations, possibly because they came up later. They are not compatible with any decompression program or application. However, their main advantage is that they reduce the files' size to a minimum. Still, the differences are not very significant. In both cases, the original content of compressed or decompressed files is not affected and can be easily stored and shared.
Programs and applications to compress and decompress files
With the following list, we will prioritize specific programs and applications for Microsoft and Android environments. In some cases this apps can also be used on Linux. In the last section, we will show some of the most popular ones for MAC/iOS.
7-Zip
7-Zip is a free, open-source file compression and decompression software under the GNU LGPL license. Today, it is the most popular free program because of:
- efficiency
- simplicity
- a high degree of compatibility.
It works with its own compression format (7z). Still, it supports a wide variety of formats in terms of decompression, including:
- Zip
- AB
- RAR
- ARJ
- GZIP

One of its great strengths is that it has a very simple interface that makes navigation much easier for the novice user. In a very simple way, the user can extract, compress, or visualize the files' content. It allows for the compression of enormous files. It can be useful for both companies and individuals. You can access the program through this link.
WinZip
The apps WinZip and WinRar are the most widely known file compression and decompression software, despite being paid solutions. WinZip already has 23 versions and, since its birth, has been evolving and adapting to new user needs. It is one of the most popular programs. Even though, as we mentioned, it is not free. Why would users spend money on this app if there are free alternatives? One of the main reasons is its integration with Microsoft, which makes itmuch easier for the user to compress or decompress files quickly and easily.
It also has interesting advanced options for sharing files from the program itself through a built-in option, integrating:

The app also adapts its interface to different devices, without forgetting one of the features that consumers like the most: its options for ensuring file security. It backs up and keeps files encrypted and secure. It is capable of extracting files in 13 different formats. Still, its Achilles' heel is, for the moment, that it does not compress in formats such as:
- CAB
- RAR
- LHA / LZH
Operating system requirements: Microsoft Windows 10, Windows 8, Windows 8.1, Windows 7, and Windows Vista.

Also, the license is valid for life. WinRar, as you may have guessed, is a software created based on the patented Rar format. Rar formats stand out for their high compression capacities (reduces the files size in a higher percentage).
WinRar is the officially authorized program for creating and compressing files in Rar formats. Still, it can decompress files in many other formats. The interface is not as attractive and intuitive as others. A free trail version is available for 40 days. You can access the download of thesoftware via this link.

- 7Z
- ARC
- GZ
- PEA
- ZIP
- XZ, and others.

What Is Compress Files
Before extracting the data from a compressed file, you must first determine the compressed file type. On an IBM compatible computer running Windows, this can be determined by the file extension. Most compressed files are either .ZIP, .RAR, .GZ, or .TGZ files. Below are examples of what some of the different compressed icons look like in Microsoft Windows.
Once the compressed file type is determined, use the appropriate program. For example, many users use WinZip and Pkzip to extract ZIP files and WinRAR to extract RAR files in Windows. However, we recommend Windows users use 7-Zip since this program is free, open source, and supports all major compressed file formats.
Note7-Zip is capable of opening most of the more common types of compressed files, including .ZIP, .GZ, .TAR, .WIM , and .XZ
TipIf you are using MicrosoftWindows XP, Vista, 7, or later, your computer should already be cable of extracting the contents of ZIP files.
TipIf you do not want to or cannot install a program on your computer, you can also compress and decompress files online.
Once a compression program is installed on the computer, you can extract the contents from the compressed file. Below are some basic steps on how you can extract files.
TipIf you are extracting a file in e-mail, save the file to a folder on the computer first.
In Microsoft Windows, locate the compressed file and right-click it. A menu should open that gives you the options to Extract or Extract all the file. Click one of these options to extract the file. A window should open with additional options, such as the location to where you want to extract the files. If you have installed 7-Zip, click 7-Zip and then Extract to 'xxxx,' where xxxx is the name of the compressed file.
CautionWhen extracting the files, pay attention to where you are extracting the files. Extracting the files to the incorrect location, such as the desktop, can extract multiple files to the desktop.
Free Zip Program
If the compressed file is for a program installation, open the folder containing the extracted files and run the setup to start the installation process.
Decompress a file in MS-DOS or the Windows command line
MS-DOS users need to extract the files using the command line. We recommend users use the pkzip and pkunzip utilities to compress and uncompress their files. Additional help and information about how files can be extracted from the command line is available on our PKZIP and PKUNZIP page.
How to decompress a compressed file in Linux and Unix
Unlike other operating systems, almost all variants of Linux and Unix come pre-installed with some form of command capable of compressing and uncompressing files. Linux and Unix users are likely to be dealing with file extensions such as .TAR, TGZ, .Z or .TAR.GZ. See the below Linux and Unix command pages for additional information about the commands used to create compressed files and to uncompress files.
