File compression is an essential skill for anyone looking to optimize storage space, improve file transfer speeds, and keep their Windows PC organized. Whether you’re clearing up space for new software, backing up important documents, or sending large files via email, mastering file compression can make your computing life much easier. This guide provides expert recommendations, practical examples, and step-by-step instructions tailored for both beginner and advanced Windows users.
What Is File Compression and Why Is It Important?
File compression reduces the size of files and folders by encoding their data more efficiently. This process not only saves valuable disk space but also speeds up file transfers and simplifies sharing. Windows users commonly encounter compressed files in ZIP, RAR, and 7Z formats.
For example, compressing a large folder of vacation photos can shrink the total size from 200 MB to just 50 MB, making it much easier to email or upload to cloud storage.
Tools Every Windows User Should Know
Windows includes basic compression tools, but third-party utilities offer more features and flexibility. Here are the top expert-recommended solutions:
1. Windows Built-in Compression (ZIP)
Right-click any file or folder, select ‘Send to’, then ‘Compressed (zipped) folder’. This creates a ZIP file that can be opened on almost any computer.
2. 7-Zip
A free and open-source tool supporting ZIP, 7Z, TAR, GZ, and more. It offers better compression ratios and advanced features.
3. WinRAR
Popular for its RAR format support and strong encryption features.
4. Glary Utilities
While primarily known for system optimization, Glary Utilities includes a File Compression module, letting you compress, encrypt, and split files directly within its all-in-one interface. It’s especially useful if you want to handle cleanup and compression in a single workflow.

How Do I Compress Files and Folders in Windows?
1. Using Windows Built-in ZIP:
– Select the file(s) or folder(s) you wish to compress.
– Right-click and choose ‘Send to’ > ‘Compressed (zipped) folder’.
– Enter a name for the compressed file and press Enter.
– That’s it—your ZIP file is ready to move, email, or store.
2. Using Glary Utilities:
– Open Glary Utilities and navigate to the ‘File Management’ section.
– Select ‘File Compression’.
– Add your files or folders, choose a destination and compression format (ZIP or 7Z), and click ‘Compress’.
– Glary Utilities even allows you to set a password for added security.
Why Use Third-Party Tools?
While Windows’ built-in compression is convenient, tools like Glary Utilities, 7-Zip, and WinRAR offer:
– Higher compression ratios (smaller files)
– Password protection for sensitive data
– Support for more formats (7Z, RAR, TAR, etc.)
– Splitting large archives into smaller parts for easier transfer

How Can I Maximize Compression Efficiency?
1. Choose the Right Format:
– 7Z generally offers better compression than ZIP or RAR, especially for large files or mixed content.
– Use 7-Zip or Glary Utilities to select the 7Z format if compatibility isn’t an issue.
2. Adjust Compression Settings:
– In 7-Zip or Glary Utilities, set the Compression Level to ‘Ultra’ for maximum savings (note: this takes more time).
– For text-heavy files (documents, code), these settings can dramatically reduce file size.
3. Split Large Archives:
– With Glary Utilities or 7-Zip, split compressed files into smaller parts (e.g., 100 MB chunks) for easier cloud uploads or flash drive transfers.
– Example: Back up a 3 GB folder by creating three 1 GB files for storage on smaller devices.
4. Secure Sensitive Data:
– Always use encryption and strong passwords when compressing personal or confidential files.
– Both Glary Utilities and WinRAR support AES-256 encryption.
5. Automate Compression in Workflows:
– Glary Utilities allows users to integrate file compression into regular cleanup routines.
– Schedule tasks to archive old downloads or temporary folders, keeping your system lean and efficient.
Troubleshooting and Best Practices
What Should I Do If a Compressed File Won’t Open?
– Ensure you have the correct software (e.g., 7-Zip for 7Z files, WinRAR for RAR).
– Check for file corruption, especially if the archive was downloaded or transferred.
– For password-protected archives, double-check the password and try again.
– Consider re-downloading the file or requesting a new copy from the sender.
How Can I Avoid Data Loss?
– Always keep uncompressed backups of critical data before compressing and deleting originals.
– Use Glary Utilities’ backup features alongside compression to create robust, recoverable archives.
– Test extracted files before deleting the originals.
Final Recommendations
File compression is a powerful tool—whether you’re a beginner managing family photos or an advanced user archiving business data. For routine tasks, Windows’ built-in ZIP functionality works well. For enhanced features, security, and automation, consider Glary Utilities as your all-in-one solution. Its integration of file compression with broader system maintenance can save you time, keep your PC running smoothly, and make file management effortless.
