How to Open a RAR File on Any Device
RAR files are everywhere — downloaded from the web, attached to emails, shared via cloud storage. But unlike ZIP files, your operating system probably can't open them natively. Understanding why, and what to do about it, saves a lot of frustration.
What Is a RAR File, Exactly?
A RAR file (Roshal Archive) is a compressed archive format created by Eugene Roshal in the early 1990s. Like ZIP, it bundles multiple files and folders into a single container while reducing their total size. Unlike ZIP, RAR uses a proprietary compression algorithm that often achieves better compression ratios — especially on large or complex file sets.
RAR files use the .rar extension. Newer versions of the format use .rar5, though most software handles both transparently. You'll also encounter multi-part RAR archives — sets of files named something like archive.part1.rar, archive.part2.rar — which are a single archive split across multiple files for easier sharing.
Why Can't You Just Double-Click a RAR File?
Windows can open ZIP files natively but has no built-in RAR support. macOS is the same — Archive Utility handles ZIP, not RAR. Linux distributions vary, but most don't include RAR extraction out of the box either.
This is because RAR is a proprietary format. The reference software (WinRAR) is commercial, and the format itself isn't open in the way ZIP is. Operating systems haven't chosen to build in support the way they have for ZIP.
The practical result: you need third-party software to extract RAR files, regardless of your device.
Opening RAR Files on Windows 🖥️
Several tools handle RAR extraction on Windows:
| Tool | License | Notable Trait |
|---|---|---|
| WinRAR | Trialware (technically paid) | The original; created by the same developer as RAR |
| 7-Zip | Free, open-source | Widely trusted; handles dozens of formats |
| PeaZip | Free, open-source | More visual interface; good format support |
| Bandizip | Free (with ads) / Paid | Fast extraction; clean UI |
7-Zip is a common go-to because it's completely free, regularly updated, and integrates into the Windows right-click context menu. Once installed, you right-click a .rar file and choose Extract Here or Extract to [folder name] — the contents land exactly where you expect them.
WinRAR installs similarly and integrates with the shell. It operates as trialware — the trial technically never expires, but it prompts for purchase. It opens .rar and .rar5 files natively since it's built by the same team.
For multi-part archives, open only the first file (part1.rar). The software automatically sequences through the remaining parts, provided they're all in the same folder.
Opening RAR Files on macOS
macOS users have a few solid options:
- The Unarchiver — a free app available through the Mac App Store. It's lightweight, handles RAR and many other formats, and integrates with Finder so RAR files open by default when double-clicked.
- Keka — another well-regarded option, available free from the developer's website or paid through the App Store (same app, the App Store version supports the developer).
- Archive Utility won't work for RAR — don't waste time trying.
Installation is straightforward: install the app, and it registers itself as the default handler for .rar files. From there, double-clicking a RAR file extracts it, usually to the same folder.
Opening RAR Files on Linux
Linux users typically work from the terminal or use a file manager with archive plugin support.
From the command line, the unrar package handles extraction:
unrar x archive.rar The x flag preserves the internal folder structure. Most package managers (apt, dnf, pacman) include unrar in their repositories — install it with your standard package manager command.
Graphically, file managers like Nautilus (GNOME) or Dolphin (KDE) can extract RAR files once the appropriate archive plugin is installed (often file-roller on GNOME-based systems).
Opening RAR Files on Mobile 📱
Android has several capable file manager apps that include RAR support — RAR for Android (made by the same team as WinRAR) and ZArchiver are frequently used options. Both are free in the Play Store.
iOS is more limited by the sandboxed file system, but apps like iZip or Documents by Readdle handle RAR extraction and integrate with the Files app.
On mobile, the experience varies more than on desktop. Large archives or multi-part RAR sets can be slower to handle, and where the extracted files land depends on the app's storage permissions and your device's folder structure.
Variables That Affect Your Experience
How smoothly this goes depends on several factors:
- Operating system version — newer Windows and macOS versions may shift what's natively supported over time
- Archive size and part count — large or multi-part archives take longer and require all parts present
- Password-protected RARs — all the tools above support password-protected archives, but you need the password the creator set
- RAR version — older tools may struggle with
.rar5files; checking that your software is up to date matters - File integrity — a partially downloaded or corrupted RAR file will fail extraction regardless of what software you use; most tools report a checksum error in that case
The right tool for extracting a small occasional RAR file on a personal laptop looks different from a workflow involving frequent large multi-part archives on a shared workstation. Your OS, how often you deal with RAR files, and how much control you want over extraction behavior all shape which approach actually fits.
