What is the easiest way to clean up computer storage?

With the large file sizes of photos, videos, music and more filling up hard drives quicker than ever, it’s becoming increasingly important to free up space on your computer. Cleaning up your computer’s storage can seem like a daunting task, but it doesn’t have to be. By following some simple tips, you can easily reclaim gigabytes of space and keep your computer running smoothly.

Why is it important to clean up computer storage?

There are several key reasons why you should periodically clean up the storage on your computer:

  • Improve performance – When your hard drive is near full capacity, your computer has to work much harder to read, write, and access files. This can lead to slowdowns, crashes, and other performance issues.
  • Prevent data loss – Running out of space can sometimes cause files to become corrupted or lost. Cleaning up space proactively helps avoid this.
  • Free up room for new files – Whether it’s new photos, music, or applications, you need available storage space to add content to your computer. Removing unneeded files makes room for the stuff you really want.
  • Remove clutter – Excess files, especially duplicates, obsolete files, and temporary files, clutter up your hard drive and make it hard to find what you need.

Regularly cleaning up and organizing your storage gives you the breathing room you need to operate smoothly and minimize frustrations.

How can you find out what’s taking up space?

Before you can clean up your storage, you need to understand what’s occupying all that space. Here are some ways to analyze storage on Windows and Mac computers:


  • Open File Explorer and look under This PC to see an overview of space usage on each drive.
  • Right-click on the drive and select Properties to view detailed storage usage graphs and statistics.
  • Use the Storage Sense feature to get a detailed storage analysis and cleanup recommendations.
  • Download third-party tools like TreeSize Free or WinDirStat to visually map disk usage and pinpoint big files and folders.


  • Click on About This Mac and go to the Storage tab to see an overview of storage usage per drive or category.
  • Use Finder’s Smart Folders to locate files over a certain size or date.
  • Download DaisyDisk or Disk Inventory X third-party apps for more detailed usage mapping.
  • Go to Settings > Battery to manage iCloud storage.

Taking advantage of these built-in features and tools makes it easy to get visibility into exactly what’s consuming all that space. Once you identify the storage hogs, you can take action.

What are some quick ways to free up space?

If you need to quickly reclaim some storage, here are some techniques that can make an immediate dent:

Empty the Recycle Bin

Files deleted from your hard drive get temporarily stored in the Recycle Bin. Emptying it removes these files permanently and can recover gigabytes of space. Just right-click the Recycle Bin and select Empty.

Remove temporary files

Web browsers, apps, and even Windows and MacOS create temporary files for caching, storing temporary data, and more. These usually get cleared automatically but sometimes don’t. Use the Disk Cleanup utility on Windows or a third-party cleaner app like CleanMyMac to purge temporary files.

Delete unneeded downloads

Over time, your Downloads folder fills up with installation files, PDFs, digital media files, and other downloaded items you don’t need anymore. These can usually be safely deleted.

Clean up System Restore

Windows System Restore protects your system by saving snapshots of critical system files, but these can consume significant storage space. Use its interface to delete unneeded restore points and reduce the allocated space for snapshots.

Uninstall unused apps

Often there are applications you no longer use but are still taking up precious space. Uninstall these programs to recover storage real estate and improve system performance.

Store files in the cloud

Cloud storage services like Dropbox, Google Drive, Microsoft OneDrive, and iCloud allow you to move files off of your main hard drive. Putting media files, documents, and other data in the cloud frees up local storage capacity.

What are some preventative measures you can take to avoid clogging up your computer?

In addition to cleaning already consumed space, you can take some proactive measures to help minimize storage usage bloat:

  • Delete unused programs – If you installed a program you no longer need, fully uninstall it.
  • Clear cache files – Configure apps and browsers to automatically clear unneeded cache data periodically.
  • Move data to external storage – Use external hard drives or cloud servers to store files long-term instead of locally.
  • Delete setup installers – Uninstall an application’s setup or installer files once installation is complete.
  • Empty trash automatically – Configure your system trash to empty itself on a schedule, such as every week.
  • Unsubscribe from newsletters – Opt out of newsletters and other recurring email lists you don’t read to keep your inbox lean.
  • Use storage quotas – Set maximum storage limits for certain folders and partitions.

Implementing some of these helpful tips will go a long way towards avoiding storage-hogging file buildup.

What are some advanced ways to free up significant storage space?

When simple trimming won’t cut it, you may need to use more advanced strategies to reclaim large swaths of storage space. Here are some more aggressive techniques for major disk space cleanup:

Delete System Restore snapshots

As mentioned previously, System Restore can consume copious amounts of space with file snapshot data. Instead of just reducing its allocation, consider deleting all previous restore points. This will dramatically cut used space, although you lose the ability to restore your system to those points.

Clear cached app data

Many applications, such as web browsers, map programs, and music streaming software, use cached temporary data to improve performance. This cache can grow very large, sometimes exceeding several gigabytes. Dig into the settings menus of these apps and wipe their cache to recover that space.

Compress disks

On Windows, enabling NTFS compression on drives transparently compresses files to take up less space. While this can slow down performance, it usually increases available capacity without compromising files. MacOS offers similar compression features.

Uninstall bundled software

New PCs often come with tons of pre-installed third-party software, some of which you may never use. Uninstalling all this potentially useless bundled software can provide an easy storage boost.

Remove restore partitions

Some manufacturers create dedicated restore partitions on the hard drive to hold system recovery image files. If you have recovery media or a restoration USB drive, you can likely delete this partition and gain back that capacity.

Move user folders

Large user folders like Documents, Music, and Pictures occupy prime real estate on the main system drive by default. Moving them to a secondary data drive frees up room for apps and the operating system to benefit speed.

Delete old system restore points

In addition to clearing all restore points, you can manually delete unneeded ones more than a few weeks old to gain back capacity while keeping key recovery milestones.

Remove Windows Page File

The Windows swap file provides added virtual memory but is often over-allocated. You can shrink or fully erase it to open up free space with minimal impact for most users.

These advanced tips require more effort but are necessary when you need to maximize free disk space on a cramped drive.

What steps should you take to maintain your storage optimization?

After putting in the work to clean and optimize your computer’s storage usage, it’s important to keep up regular maintenance habits. Here are some things you can do periodically to maintain ample free disk space:

  • Delete browser cache – Set your web browser to auto-clear cache and site data every month.
  • Remove unneeded downloads – Make it a habit to manually delete old downloads you no longer need.
  • Cleanup apps – Use a storage and cleanup utility to find new junk files every few weeks.
  • Review installed programs – Uninstall apps and games you haven’t used in awhile.
  • Offload to the cloud – Continuously upload media files and docs to cloud storage.
  • Empty trash and recycle bin – Develop a habit of permanently deleting your deleted files every week or so.

Setting reminders and dedicating a bit of time each month to actively maintain your storage can prevent creeping file buildup before it becomes an issue again.


With the ever-increasing file sizes from media, apps, games, and operating systems, getting in control of your PC’s storage is crucial. While it may seem intimidating, following the tips in this guide makes it a breeze to clean out gigabytes of accumulated digital junk in almost no time. Implementing preventive maintenance steps keeps your computer’s precious storage optimized for the long-haul.

So don’t let that hard drive remain a bloated, disorganized mess. Get organized and reclaim your disk space today. Your computer will run smoother, boots will be faster, and you’ll breathe easier knowing there is plenty of room for all your important files.
