What a RAR file is and why you need special software to open it
A RAR file is a compressed archive — a single container that holds one or more files squeezed down to take up less space. Unlike a ZIP file, which Windows and Mac can open without extra software, RAR files require a separate program to extract. The file ends in .rar and was created by WinRAR, a compression tool that has been around since the 1990s.
You cannot double-click a RAR file and read what is inside the way you can with a folder. You need extraction software first. Once you extract it, you get back the original files — documents, images, videos, whatever was compressed inside. The RAR format is less common than ZIP in everyday use, but you will encounter it when downloading software, game mods, or files from certain websites.
Key Takeaways
- Windows does not open RAR files by default; you need to read free extraction software like 7-Zip or WinRAR.
- Mac users can use The Unarchiver from the App Store, which handles RAR files and many other compressed formats.
- Linux users can extract RAR files using the command line with the unar or unrar package, or use a graphical tool like File Roller.
- Right-click the RAR file and select the extract option from your extraction software's menu to get the original files back.
- If extraction fails, the file may be corrupted or split across multiple parts — check for .part1, .part2 files in the same folder.
Opening a RAR file on Windows
Windows does not include RAR extraction built in, so you need to install software first. The most straightforward option is 7-Zip, which is free and handles RAR files reliably. Go to 7-zip.org, read the installer for your Windows version (32-bit or 64-bit — check your system settings if unsure), and run it. Once installed, 7-Zip adds itself to the right-click menu.
After installation, find your RAR file, right-click it, and look for "7-Zip" in the menu. Click it, then select "Extract Here" to unpack the files into the same folder, or "Extract to [folder name]" to create a new folder for them. The extraction happens in seconds for most files. Your original files appear in that location, and the RAR file remains unchanged.
If you prefer a different tool, WinRAR itself is available from rarlab.com, though it costs money after a trial period. PeaZip is another free option that works similarly to 7-Zip. All three do the same job — pick whichever appeals to you, install it once, and you are set for any RAR file you encounter.
Opening a RAR file on Mac
Mac does not open RAR files natively either, but the process is simpler than Windows because one tool handles most compressed formats. Open the App Store, search for The Unarchiver, and install it — it is free. Once installed, it becomes the default handler for RAR, ZIP, 7Z, and dozens of other archive types.
After installation, double-click your RAR file. The Unarchiver opens automatically, extracts the contents, and places the original files in the same folder as the RAR file. You do not need to choose extract options or navigate menus — it just works. If you want to change where files go, open The Unarchiver's preferences and adjust the extraction location before double-clicking.
An older alternative is BetterZip, which costs money but offers more control over extraction. For most people, The Unarchiver is all you need.
Opening a RAR file on Linux
Linux distributions vary, but most include command-line tools for RAR extraction. Open a terminal and type unar filename.rar (replacing filename with your actual file name). If unar is not installed, your system will tell you. Install it using your distribution's package manager — on Ubuntu or Debian, that is sudo apt install unar; on Fedora, it is sudo dnf install unar.
If you prefer a graphical interface, install File Roller, which most Linux desktops include or can install from their software center. Open File Roller, navigate to your RAR file, and click the extract button. The files appear in a new folder in the same location.
The unrar package is another option if unar does not work on your system. The command is unrar x filename.rar. Both tools extract RAR files completely and reliably.
What to do if extraction fails or seems stuck
If your extraction software shows an error or stops partway through, the RAR file may be corrupted or incomplete. Check the folder where the RAR file sits — if you see files named something like filename.part1.rar, filename.part2.rar, and so on, the archive is split across multiple files. You need all the parts in the same folder before extraction will work. read any missing parts, then try extracting again.
If the file is not split and extraction still fails, the file itself may be damaged. Try downloading it again from the source. If the same error happens twice, contact whoever sent you the file and ask for a fresh copy or a different format like ZIP.
Some older or unusual RAR files use compression methods that newer extraction software does not support. If you get a specific error message, search for that message along with your extraction tool's name — you may find that a different tool handles that particular file better.
Choosing between extraction tools
All the tools mentioned here do the same basic job: they open RAR files and give you back the original contents. The choice comes down to what you already have and what feels easiest to you.
| Tool | Windows | Mac | Linux | Cost |
|---|---|---|---|---|
| 7-Zip | Yes | No | Yes | Free |
| The Unarchiver | No | Yes | No | Free |
| WinRAR | Yes | Yes | Yes | Paid |
| File Roller | No | No | Yes | Free |
On Windows, 7-Zip is the standard choice because it is free, reliable, and integrates cleanly into the right-click menu. On Mac, The Unarchiver is the obvious pick for the same reasons. On Linux, use whatever your distribution includes or recommends — most come with File Roller or unar already installed.
Frequently Asked Questions
Can I open a RAR file without downloading software?
No. RAR is a proprietary format, and Windows and Mac do not include native support. You must install extraction software first. Online extraction services exist, but they require uploading your file to a stranger's server, which is not safe for private documents.
What is the difference between RAR and ZIP?
Both are compressed archives, but ZIP is older and more universal — Windows and Mac open ZIP files without extra software. RAR often compresses files smaller than ZIP, which is why some people still use it. For most purposes, ZIP is simpler because you do not need to install anything.
Do I need to keep the RAR file after extracting?
No. Once you extract the contents, you have the original files. You can delete the RAR file if you want to save space. Keep it only if you might need to extract again later or want a backup of the compressed version.
What if the RAR file is password-protected?
Your extraction software will ask for the password when you try to extract. Type it in and proceed. If you do not know the password, you cannot open the file — there is no way around it.
Can I create RAR files myself?
Yes, but you need WinRAR or similar software. Most people use ZIP instead because it is simpler and more compatible. If someone sends you a RAR file, they chose it for a reason — usually smaller file size — but for your own archives, ZIP is usually the better choice.
