WinRARis a trialware file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats,[6] and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives.
WinRAR is a Windows-only program. An Android application called "RAR for Android" is also available.[7] Related programs include the command-line utilities "RAR" and "UNRAR"[8] and versions for macOS,[4] Linux, FreeBSD, Windows CE, and MS-DOS.
RAR/DOS started as a mix of x86 assembler and C, with the amount of assembly code decreasing over time and moving to pure C/C++ later on. The first versions of WinRAR were written in C, modern versions are using C++. RAR for Android is written as a mixture of Java and C++.[1]
WinRAR and the RAR file format have evolved over time. Support for the archive format RAR5, using the same RAR file extension as earlier versions, was added in version 5.0;[9] the older RAR file format has since been referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives;[10] only older versions of WinRAR run on Windows versions prior to Windows Vista, and cannot open RAR5 archives.
The RAR5 file format - from version 7 on, referred to as "RAR" - increased the maximum dictionary size up to 64 GB, depending on the amount of available memory, with the default in version 5 increased from 4 MB to 32 MB, typically improving compression ratio.For dictionaries larger than 4 GB, the size can be specified if it is unequal to a power of 2. Thus, there are no restrictions to the range 4, 8, 16, 32, 64, allowing 5 GB or 22 GB to be chosen at will. Archives with dictionaries larger than 4 GB can only be extracted by WinRAR 7.0 or newer.AES encryption, when used, is in CBC mode and was increased in strength from 128- to 256-bit. Maximum path length for files in RAR and ZIP archives is increased from 2047 to 65535 characters.[10]
Options added in v5.0 include 256-bit BLAKE2 file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, and Quick Open record to allow large archives to be opened faster.[10]
The RAR5 file format removed comments for each file (though archive comment still remains), authenticity verification, and specialized compression algorithms for text and multimedia files. RAR5 also changed the file name for split volumes from "archivename.rNN" to "archivename.partNN.rar".[10]
The RAR7 file format added support for 64GB compression dictionary and improved compression ratio by adding two extra algorithms. RAR7 archives with dictionary sizes up to 4GB can be unpacked by previous versions of WinRAR (5.0 and above) given there's enough RAM.
The software is distributed as "try before you buy"; it may be used without charge for 40 days.[2] When the period expires, the non-enterprise functionalities remain available, a move intended to discourage piracy.[5] In China, a free-to-use personal edition has been provided officially since 2015.[16]
Although archiving with the RAR format is proprietary, RARLAB supplies as copyrighted freeware the C++ source code of the current UnRAR unpacker, with a license allowing it to be used in any software, thus enabling others to produce software capable of unpacking, but not creating, RAR archives.[17]
In February 2019, a major security vulnerability in the unacev2.dll library which is used by WinRAR to decompress ACE archives was discovered.[18][19] Consequently, WinRAR dropped the support for the ACE format from version 5.70.
Self-extracting archives created with versions before 5.31 (including the executable installer of WinRAR itself) are vulnerable to DLL hijacking: they may load and use DLLs named UXTheme.dll, RichEd32.dll and RichEd20.dll if they are in the same folder as the executable file.[10][20]
It was widely reported that WinRAR v5.21 and earlier had a remote code execution (RCE) vulnerability which could allow a remote attacker to insert malicious code into a self-extracting executable (SFX) file being created by a user, "putting over 500 million users of the software at risk".[21] However, examination of the claim revealed that, while the vulnerability existed, the result was merely an SFX which delivered its payload when executed; published responses dismissed the threat, one saying "If you can find suckers who will trust a .exe labelled as self-extracting archive ... then you can trick them into running your smuggled JavaScript".[22][23]
Due to the recent vulnerability, I've created a quick deployment package to update or install Winrar to the latest version.
Please note that this is a simple install and I haven't tested it with a licensed version.
So if I understand correctly, it is legal (legality is where I like to draw the line, though I like to be a nice guy sometimes as well) to use the trial version of sublime indefinitely (or maybe an arbitrary period like 1,000,000 years)?
The majority of license purchases Sublime gets is most likely from companies. This is because there are huge legal and financial implications if a company is found to be using pirated software. So why would companies want to buy swaths of Sublime licenses instead of telling its employees to just use Notepad++, Vim, or Emacs? Because the engineers in those companies probably downloaded the trial version of Sublime in college or whenever, learned how to use it, and feel most comfortable and efficient using it over other editors. Obviously companies want their engineers to be as efficient as possible so an $80 license is completely worth the productivity gains.
The developers of Sublime Text likely understand that not everyone who downloads the software will purchase a license. However, by providing a generous evaluation period and allowing users to continue using the software without interruptions, they hope to encourage users to purchase a license to support ongoing development.
is there any software very similar to WinRAR that is for linux? in specific for ubuntu 18.04 mate, preferably having a visual interface or contextual menu when you right click on a .rar, thanks, I'm new to linux
Have you tried file roller ? It's installed by default in Ubuntu (not sure about Ubuntu Mate, so.....) ; It's a graphical tool for extracting and compacting files and works by right clicking ,just as winrar in windows.
Try searching for it in the store , or install synaptic package manager and search for "file-roller" (without quote marks). I also recommend you to install the "unrar" package found in synaptic , non-free version. If you can't find the app store in your system, you can install synaptic by typing in the terminal:
WinRAR is a free app with which you can compress and decompress any file on your computer in a simple and effective way.

It also has high compression and decompression speeds to help you extract files from compressed formats in the shortest possible time. To decompress anything on your computer, regardless of its format, just double-click its icon.
WinRAR supports various formats, so you can always work with ZIP, RAR, or 7Z files. Beyond that, when compressing your files, this tool supports CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, and ISO formats, among many others. This app's versatility makes it an indispensable tool for your day-to-day life.
When working with this tool, you can encrypt your documents with Rinjdael (AES-128), digital signatures, or modification blocking. With this additional layer of security, you can protect your personal information when compressing, decompressing, or transferring your documents.
Yes, WinRAR is a safe program, although older versions may have security flaws that have subsequently been fixed. That said, while WinRAR is safe, that's not necessarily true for the file you unzip with it.
Yes, you can continue to use WinRAR for free after the trial period, although each time you use it, a window will pop up informing you that your trial is over and direct you to purchase the full version of WinRAR from their website.
Uptodown is a multi-platform app store specialized in Android. Our goal is to provide free and open access to a large catalog of apps without restrictions, while providing a legal distribution platform accessible from any browser, and also through its official native app.
