How to Free Up Space on Your Computer

Written by: Jay H.

Running out of hard drive space can significantly slow down your computer, impact performance, and make it challenging to save new files or install software. Whether you’re working with limited storage or just want a more efficient system, managing and freeing up space on your hard drive can make a big difference. Here’s a comprehensive guide to help you declutter your drive and optimise storage.

Why Freeing Up Drive Space is Important

When your drive is full, your computer has to work harder to locate and organise data, which can cause performance issues like slow startup times, lag, and system crashes. By freeing up space, you’re making more room for essential files, programs, and system operations that keep your computer running smoothly.

How to Free Up Disk Space

Check Your Storage Space

First, it’s helpful to understand where your space is being used so you can target areas that need the most attention.

• Windows:
  • Go to Settings > System > Storage.
  • Here, you’ll see a breakdown of how your hard drive is being used by categories like Documents, Photos, and Apps.
• macOS:
  • Go to Apple menu > About This Mac > Storage.
  • This section provides a visual overview of your storage use, so you can quickly see what’s taking up the most space.

Use Built-in Tools to Free Up Space

Both Windows and macOS offer built-in tools that can automatically clean up unnecessary files.

Windows Disk Cleanup Tool

1. Search for Disk Cleanup in the Windows search bar and open the tool.
2. Select the drive you want to clean up (usually C: for most users).
3. The tool will scan for temporary files, system cache, and other unneeded files.
4. Review the list, check the boxes of items you want to delete (like Temporary Internet Files and Recycle Bin), and click OK to free up space.

macOS Storage Management Tool

1. Go to Apple menu > About This Mac > Storage > Manage.
2. Here, you’ll find options like Store in iCloud (which moves files to iCloud), Optimize Storage (removes iTunes movies and TV shows you’ve already watched), and Empty Trash Automatically.
3. Select each option and enable it based on your storage needs.

Uninstall Unnecessary Applications

Over time, software and apps you no longer use can build up, occupying valuable space on your hard drive.

• Windows:
  • Go to Settings > Apps > Apps & features.
  • Click on the apps you no longer need, then select Uninstall.
  • If prompted in a dialog box, continue to uninstall the program until it has been removed.
• macOS:
  • Open Finder and go to Applications.
  • Drag any unnecessary apps into the Trash and empty the trash to free up space.

Clear Out Your Downloads Folder

Downloads can quickly pile up and go unnoticed. Files like installers, PDFs, and media that you only needed temporarily might still be sitting there.

1. Open your Downloads folder.
2. Review the files and delete any items you no longer need.
3. Consider organising the remaining files into folders or moving them to an external drive if they’re important.

Move Large Files to External Storage or Cloud Storage

For larger files, such as videos, high-resolution photos, and extensive documents, consider moving them off your computer entirely.

• External Drives: Transfer large files to an external hard drive to free up space on your computer. This also serves as a backup.
• Cloud Storage: Services like Google Drive, Dropbox, and iCloud provide storage that doesn’t occupy physical space on your computer, allowing you to access files from any device.

Use Storage-Saving Formats and Settings

If you work with media, try using compressed formats or settings to reduce file size without losing quality.

• Photos: Use JPEG instead of PNG for photos unless you need transparency. On macOS, Preview allows you to resize images and save them in compressed formats.
• Videos: Use software like HandBrake to compress video files without sacrificing quality.
• Documents: Save Word documents in PDF format if they don’t require frequent editing, as PDFs can often take up less space.

Set Your Trash to Empty Automatically

Leaving files in the trash doesn’t free up space—they’re still stored on your hard drive. Setting your system to empty trash automatically can save you this step.

• Windows:
  • Go to Settings > System > Storage, then click on Storage Sense and enable it to automatically empty your recycle bin based on your preferences.
• macOS:
  • Go to Apple menu > About This Mac > Storage > Manage, and turn on Empty Trash Automatically.

Start Managing Your Drive Space

Managing your hard drive space doesn’t have to be a hassle. With a combination of using built-in tools, deleting unnecessary files, and transferring large items to external or cloud storage, you can keep your computer performing at its best. Whether you’re aiming to free up space for a new project or improve system speed, these steps make it easier to create a streamlined, efficient workspace.
