Managing files efficiently is a crucial aspect of maintaining a healthy and organized Windows PC. File compression is one of the most effective ways to save disk space, speed up file transfers, and streamline backups. Whether you’re a beginner learning the basics or an advanced user seeking more powerful tools, this guide will walk you through step-by-step file compression techniques tailored for Windows users.
What Is File Compression and Why Should You Use It?
File compression reduces the size of files and folders by encoding their data more efficiently. This allows you to:
– Save valuable disk space
– Send large files as email attachments
– Speed up uploads and downloads
– Organize backups or archives
– Reduce storage costs on cloud platforms
Windows offers built-in compression features, but there are also third-party tools that provide advanced functionality, better compression ratios, and support for multiple formats.

How Do I Compress Files or Folders Using Windows Explorer?
1. Select the files or folders you wish to compress.
2. Right-click the highlighted items.
3. Choose “Send to” from the context menu, then click “Compressed (zipped) folder.”
4. A new ZIP file will appear in the same location. Rename the archive if desired.
Real-World Example:
Suppose you want to email a folder containing vacation photos. Rather than attaching each file, compress the folder into a single ZIP file and send it as one attachment.
How Do I Extract Files from a ZIP Archive?

Why Use Tools like 7-Zip or WinRAR?
Windows’ built-in ZIP format is convenient, but third-party tools offer better compression and support for formats like 7z, RAR, and TAR.
Step-by-Step: Compressing with 7-Zip
1. Download and install 7-Zip (free from https://www.7-zip.org/).
2. Right-click the files or folders to compress.
3. Hover over “7-Zip” in the context menu.
4. Select “Add to archive…”
5. Choose your desired archive format (e.g., 7z for maximum compression).
6. Adjust compression level as needed. “Ultra” provides the smallest file size but may take longer.
7. Click “OK” to create the archive.
Example:
Compress a folder full of PDF manuals using 7z format to reduce size before uploading to cloud storage.
How to Extract from Multiple Archive Formats
1. Right-click the archive file (ZIP, RAR, 7z, etc.).
2. Choose “7-Zip” > “Extract Here” or “Extract to [Folder Name]\.”
3. Access your files in the extracted location.

How Can I Compress Multiple Folders at Once?
Using 7-Zip’s command line tool:
1. Open Command Prompt.
2. Navigate to the directory containing the folders.
3. Use the following command:
7z a -tzip ArchiveName.zip Folder1 Folder2 Folder3
This creates a ZIP archive containing the listed folders.
How to Encrypt Archives for Security
1. In 7-Zip’s “Add to archive…” window, set a password in the “Encryption” section.
2. Choose encryption method (AES-256 is most secure).
3. Click “OK.” The archive now requires a password to open.
Why Use Glary Utilities for File Compression Management?
If you’re looking for all-in-one management and optimization, Glary Utilities is a powerful option. While its main features focus on system cleanup and performance, it also helps manage compressed files:
– File splitter and joiner: Break large archives into smaller pieces for easier storage or sharing.
