Ways to free up hard disk space on Windows


free up hard disk space

For years, hard disks got bigger and bigger, and operating systems and applications grew larger, taking advantage of the increased disk space by adding new features. Then, hard disks were replaced by SSDs with much lower capacities and suddenly space became an issue again.

If you have an SSD that’s quickly filling up, or you just need to free space on your hard drive, here’s how to give your hard disk a cleanup and get rid of files you don’t need.

Empty the Recycle Bin

This is the place to start. The Recycle Bin is a folder, like any on your PC. Files and folders in there take up room on your computer. Only when you empty the Bin are the files deleted. So the first step in freeing up space on Windows is to empty the Recycle Bin.

Use Disk Cleanup

Windows includes a built-in tool that will clean temporary files and get rid of other data you don’t need.

  1. Go to File and right-click on your C: drive
  2. Choose Properties
  3. Go to the General tab and click Disk Cleanup
  4. Wait for Windows to hunt down temporary file, Recycle Bin items, and anything else it thinks you can safely delete
  5. When it’s finished, you’ll notice that lots of files are marked for removal, but you can also check the box next to System Error Memory Dump files
  6. Select Clean up system files
  7. In the next window, under System Restore and Shadow Copies, click Clean up

This option deletes everything except the most recent restore, so if you’re computer is working fine, your safe to use that. If it’s not, don’t press that button

Activate Storage Sense

If you’ve been installing Windows 10 updates, you may have noticed that 2017’s Creators Update came with a feature called Storage sense. It automatically deletes temporary files that are no longer needed, as well as removing files that have been in the Recycle bin for 30 days or more.

  1. Click on the Start menu and choose Settings
  2. Choose System then Storage
  3. Toggle the switch under Storage sense to the on position

Get rid of Temporary files and Downloads

  1. Go to Settings System Storage
  2. Click on This PC at the top
  3. Check the boxes for Temporary files and Downloads folder
  4. Select Remove files

Uninstall programs

Uninstalling programs could free up a considerable amount of hard disk space. The exact amount will depend on how much space a program uses, and that varies from application to application. Obviously, it makes more sense to start with the largest programs you no longer need.

 To uninstall a program:

  1. Click on the application you want to uninstall
  2. Press Uninstall or Change a Program
  3. Follow the on-screen instructions

That all sounds like a long, frustrating process. However you can free up disk space using one tool, which will save you much time and decrease the risk of mistakes.
