Freeing Up Disk Space by Compressing Files

Purpose

Reduce low disk space issues by enabling disk compression on a Windows computer, allowing more storage without deleting important files.

What You’ll Need

• A Windows 10 or Windows 11 computer

• Administrator access

• Internet connection (optional, for updates or cloud backup before making changes)

Step-by-Step Guide

1. Check Available Disk Space

   • Open File Explorer.

   • Click This PC → check the storage bar under your C: drive.

2. Open Disk Properties

   • Right-click the C: drive (or the drive with low space).

   • Select Properties.

3. Enable Disk Compression

   • In the General tab, check the box Compress this drive to save disk space.

   • Click Apply.

   • Choose Apply changes to drive, subfolders, and files.

   • Wait for Windows to compress files (may take several minutes).

4. Run Disk Cleanup (Optional)

   • In the same Properties window, click Disk Cleanup.

   • Select temporary files, system cache, and Recycle Bin items.

   • Click OK → Delete Files.

5. Restart the Computer

   • Restart your computer to ensure changes take effect.

6. Verify Results

   • Recheck This PC in File Explorer.

   • Confirm additional space has been freed on the drive.

Tips for Best Practice

• Compressing files may slightly reduce performance when opening large files.

• Regularly clear temporary files and downloads to maintain space.

• Store large files in OneDrive, SharePoint, or Dropbox instead of the local drive.

• Avoid compressing system-critical folders manually unless guided by IT.

• If disk space issues persist, consider upgrading your hard drive or moving data to cloud storage.
