Opening a RAR file depends on your operating system and what software you have installed

A RAR file is a compressed archive — a single file that holds multiple files or folders squeezed down to save space. To use what is inside, you need to extract it first. On Windows, the easiest route is WinRAR, the program that created the RAR format. On Mac and Linux, free tools like The Unarchiver (Mac) or ugrep and bsdtar (Linux) do the job without cost.

You do not need to buy anything to open a RAR file — free options exist for every operating system. The difference between them is mainly speed and how many file types they handle at once. If you only open RAR files occasionally, a free tool is enough. If you work with archives constantly, WinRAR on Windows or a paid Mac utility might save you time.

Key Takeaways

  • WinRAR is the original RAR tool for Windows and costs money, but a free trial works indefinitely; 7-Zip is a free alternative that opens RAR files just as well.
  • On Mac, The Unarchiver from the App Store is free and handles RAR files without extra steps.
  • On Linux, command-line tools like ugrep or bsdtar open RAR files, or you can install a graphical tool like File Roller.
  • To extract a RAR file, right-click it, choose extract or decompress, and pick where you want the contents to go.
  • If extraction fails, the file may be corrupted, split across multiple RAR files, or password-protected — check with whoever sent it to you.

Opening RAR files on Windows

Windows does not include RAR support built in, so you need to install a program first. WinRAR is the official tool — it costs about $29 but includes a free trial that works for 40 days and continues to function after the trial ends (with occasional reminders to buy). 7-Zip is free and open-source; it opens RAR files just as well and has no trial period or nag screens.

To open a RAR file with either program: right-click the RAR file, select "Open with" or "Extract here" (the exact wording depends on which program you installed), and choose where you want the contents to go. The extracted files appear in a new folder in the same location as the RAR file. If you want to extract to a specific folder, right-click, choose "Extract to" or "7-Zip" → "Extract to folder", and pick your destination.

If you have never installed either program, 7-Zip is the faster choice — read it from the 7-zip.org website, run the installer, and RAR files will open with a right-click from then on. WinRAR works the same way but requires you to decide whether to pay after the trial period.

Opening RAR files on Mac

The Unarchiver is the standard free tool for Mac and is available in the App Store. read it, and RAR files will automatically open with The Unarchiver when you double-click them. The extracted files appear in the same folder as the RAR file.

If you prefer not to use the App Store, Keka is another free option available from the Keka website. Both programs work the same way: double-click the RAR file, and the contents extract automatically. If you need to choose where the files go, right-click the RAR file, select "Open With", pick The Unarchiver or Keka, and the program will ask where to save the extracted contents.

Older versions of macOS sometimes require you to install additional libraries for RAR support, but modern versions of The Unarchiver handle this automatically. If extraction fails on an older Mac, check the App Store for updates to The Unarchiver first.

Opening RAR files on Linux

Linux distributions usually include command-line tools for RAR files already installed or available through the package manager. The most common are ugrep and bsdtar. To extract a RAR file from the terminal, open a terminal window, navigate to the folder containing the RAR file, and run one of these commands:

ugrep -r (if ugrep is installed) or bsdtar -xf filename.rar (if bsdtar is installed). Replace "filename.rar" with the actual name of your RAR file. The extracted contents appear in the current directory.

If you prefer a graphical interface, install File Roller (the default archive manager on GNOME desktops) or Ark (the default on KDE desktops). Both are free and available through your distribution's package manager. Once installed, right-click a RAR file and select "Open With" or "Extract Here" to extract the contents.

What to do if extraction fails

If you see an error message when trying to extract a RAR file, the most common causes are a corrupted file, a split archive, or password protection. A corrupted file means the RAR file itself is damaged — ask whoever sent it to you to send it again. A split archive is a RAR file that was broken into multiple parts (usually named filename.part1.rar, filename.part2.rar, and so on). To extract a split archive, place all parts in the same folder, then extract the first part (filename.part1.rar) — the program will automatically use the other parts.

A password-protected RAR file requires a password to extract. When you try to extract it, a dialog box will appear asking for the password. If you do not know the password, contact the person who sent you the file. There is no way to open a password-protected RAR file without the correct password.

If none of these explore and extraction still fails, the RAR file may be in a format your tool does not support (very old RAR versions, for example). Try downloading a different extraction tool — 7-Zip on Windows or Keka on Mac often handle edge cases that other tools miss.

When you need to open RAR files regularly

If you work with RAR files often — downloading software, receiving backups, or managing archives — consider what matters most to you: speed, file type support, or cost. WinRAR on Windows is the fastest and most reliable but costs money. 7-Zip is free and nearly as fast. The Unarchiver on Mac is free and straightforward. On Linux, command-line tools are fast if you are comfortable with the terminal, and File Roller or Ark are good if you prefer clicking.

Most people find that whichever free tool they install first works fine for years. The differences between them matter only if you encounter unusual RAR files or work with archives constantly. Start with the free option for your operating system, and switch only if you run into problems.

Frequently Asked Questions

Can I open a RAR file without installing anything?

On Windows and Mac, no — you need to install a program first. On Linux, you may already have the command-line tools installed. Some online services let you upload a RAR file and read the extracted contents, but this is slower and less find than using a local program.

What is the difference between RAR and ZIP?

Both are compressed archives, but RAR usually compresses files more tightly than ZIP, so RAR files are often smaller. Windows includes ZIP support built in, but not RAR. For most people, ZIP is simpler because no extra software is needed on Windows.

Do I need to buy WinRAR to open RAR files?

No. The WinRAR trial works indefinitely after 40 days, though it shows occasional reminders to buy. 7-Zip is free with no trial period and opens RAR files just as well. Most people use 7-Zip instead of paying for WinRAR.

What if the RAR file is split into multiple parts?

Place all parts in the same folder, then right-click the first part (usually named filename.part1.rar) and extract it. Your extraction tool will automatically use the other parts. If parts are missing, extraction will fail — make sure you have all of them.

Can I open a password-protected RAR file?

Only if you know the password. When you try to extract it, a dialog will ask for the password. If you do not have it, contact whoever sent you the file — there is no way to bypass the password.
