7-zip how to Use

Updated: June 4, 2026 · Full review · Alternatives · Archivers

Extract, compress, and manage archives on Windows with 7-Zip—a free tool that handles the 7z compression format and over a dozen other file types without requiring paid upgrades or subscriptions.

Getting Started: Installation and Setup

Download and Install on Windows

Start by downloading the installer from the official source. Version 26.00 supports both 32-bit and 64-bit Windows systems, so choose the version matching your architecture. Run the installer and follow the setup wizard—it takes under a minute. Once installed, right-click any file or folder to see 7-Zip options directly in your context menu.

You can also grab the portable version if you need to run it without installation, though the standard build is more convenient for regular use on Windows 10 and Windows 11.

Basic Operations: Extracting and Compressing Files

Extract Archives Fast

Right-click any compressed file (ZIP, RAR, 7z, or others) and select "7-Zip > Extract Here" to unpack it into the current folder. Need more control? Choose "Extract to [folder name]" to automatically create a dedicated directory. This is faster than built-in Windows tools and handles damaged archives better than competitors like ExtractNow, which focuses only on extraction.

Create New Archives

Select the files or folders you want to compress. Right-click and choose "7-Zip > Add to archive." A dialog opens where you can set the archive name, format, and compression level. The 7z compression format offers superior file size reduction compared to standard ZIP—expect 10-30% smaller files for the same content.

Advanced Features Worth Knowing

Working with 7z Compression Format

The native 7z format is where this tool shines. It compresses harder than ZIP but takes slightly longer to process. For most users, the "Normal" compression level balances speed and size. Choose "Maximum" only if you're archiving files you rarely access and storage space matters.

Pro Tip: Hold Shift while right-clicking to access "7-Zip > Open archive" — this opens the archive in the file manager view, letting you browse contents without extracting. Edit, delete, or add files directly. It's faster than repacking entire archives.

Format Support

This tool handles ZIP, RAR, TAR, GZIP, BZIP2, XZ, ISO, and CAB files alongside its native format. It won't create RAR or ISO files (only extract them), but for most workflows, this limitation doesn't matter. Learn how the file manager interface simplifies archive browsing for a deeper look at navigation.

Why Choose 7-Zip Over Alternatives

Unlike Bandizip, which supports 40+ formats but with less aggressive compression, or IZArc with its repair tools, this software prioritizes compression efficiency and speed. WinRAR charges for licenses; this remains completely free with no nag screens.

The interface is straightforward but dated—don't expect modern styling. That's the trade-off for zero bloatware and no forced updates.

Common Tasks Simplified

Looking for a way to password-protect archives? Open the "Add to archive" dialog, enter a password in the encryption field, and choose AES-256. Need to split a large file? Set "Split to volumes" and specify the size. Both tasks take seconds once you know where to look.

Wrapping It Up

7-Zip how to use boils down to: download, install, right-click files, and pick your action. Whether you're extracting a single ZIP or managing dozens of compressed projects, it handles the job without friction. The learning curve is minimal, and the cost is zero. For Windows users who compress files regularly, this portable file compressor deserves space on your system.
