by

Running low on disk space can slow your computer to a crawl. If you’re wondering how to check what’s taking up storage on pc, you’re in the right place. Identifying large files and programs is the key to freeing up valuable space on your hard drive.

This guide provides clear, step-by-step methods for Windows and Mac users. You’ll learn to use built-in tools and third-party software to find and remove space-hogging items.

Let’s get started and reclaim your storage.

How To Check What’s Taking Up Storage On Pc

For Windows users, the process is straightforward thanks to integrated system tools. The primary utility you’ll use is called Storage Settings. It provides a visual breakdown of your storage categories.

Here is how to access and use it.

Using Windows Storage Settings

This is the easiest place to begin. The Storage Settings tool gives you a high-level overview of what’s consuming space on your main drive.

Follow these steps.

  1. Click the Windows Start button and select the Settings gear icon.
  2. Go to “System” and then select “Storage” from the left-hand menu.
  3. You will see a list of drives. Click on your primary drive (usually C:).
  4. Windows will analyze the drive and present a categorized breakdown after a few moments.

You will see categories like Apps & features, Temporary files, Documents, Pictures, and more. Clicking on any category will show you the specific files and allow you to manage them. For instance, under “Apps & features,” you can sort by size and uninstall programs you no longer need.

Analyzing With File Explorer

For a more hands-on approach, File Explorer offers powerful features. You can visually see which folders are the largest on your system.

This method is excellent for targeting personal files like videos, downloads, and archives.

  1. Open File Explorer by pressing Windows key + E.
  2. Navigate to “This PC” and right-click on the drive you want to analyze.
  3. Select “Properties” from the menu. A general pie chart will show used vs. free space.
  4. For deeper analysis, you can use the “Size” column in detailed view. Navigate to a folder, change the view to “Details,” and ensure the “Size” column is visible. This will show file sizes, though calculating folder sizes requires an extra step.

A more effective trick is to use the built-in search to find large files. In the search box at the top-right of File Explorer, type “size:” followed by a filter. For example, typing “size:>500MB” will show all files larger than 500 megabytes. You can then sort these results by size to find the biggest offenders.

Third Party Tools For Advanced Analysis

While Windows tools are good, third-party applications offer superior visualization. Tools like WinDirStat, TreeSize Free, or WizTree provide a treemap view.

In a treemap, each file is represented by a rectangle. The larger the rectangle, the larger the file. This makes it instantly obvious what is filling your drive. These tools scan much faster than Windows and can analyze entire drives in seconds, giving you a comprehensive picture that’s easy to understand.

Checking Storage On A Mac Computer

MacOS has its own set of intuitive tools for managing storage. The main hub is “About This Mac,” which offers both an overview and management options.

The process is just as simple as on Windows.

Using About This Mac Storage Management

This is the Mac equivalent to Windows Storage Settings. It provides a colorful, categorized bar showing your storage usage.

  1. Click the Apple logo in the top-left corner of your screen.
  2. Select “About This Mac” from the dropdown menu.
  3. Click on the “Storage” tab. You will see a bar graph showing categories like Applications, Documents, iOS Backups, and System.
  4. Click the “Manage…” button to open the Storage Management window.

The Management window offers recommendations like storing files in iCloud, optimizing storage by removing watched iTunes movies and TV shows, and automatically emptying the Trash. It also lets you review files in each category manually, making it easy to delete what you don’t need.

Finding Large Files With Finder

Finder, like File Explorer, can help you hunt down large files taking up space.

You can use the Finder search function with specific filters.

  1. Open a new Finder window.
  2. Press Command+F to open the search window.
  3. Click the “+” button next to “Save” to add a search filter.
  4. Set the first filter to “Kind” is “Document.” Then, click the “+” again to add a second filter.
  5. Set the second filter to “File Size” is “Greater than” and choose a size like 500 MB or 1 GB.

Finder will now display all documents larger than your set treshold. You can change the “Kind” filter to “Movie” or “Image” to search for other large file types. This is a precise way to locate your personal large files that might not be neatly categorized.

Using DaisyDisk Or Similar Apps

For Mac users who prefer a visual analysis, DaisyDisk is a popular and powerful choice. It presents your storage as a sunburst diagram, making it very easy to see which folders are the largest.

You simply launch DaisyDisk, select your drive, and let it scan. You can then click on segments of the diagram to drill down into folders and delete files directly from the app. There are free alternatives like Disk Inventory X that offer similar treemap functionality.

Common Storage Hogs To Look For

Certain types of files and data are notorious for consuming large amounts of space without you realizing it. Knowing where to look can save you a lot of time.

Here are the usual suspects.

Temporary And Cache Files

Your operating system and applications constantly create temporary files to speed up processes. Over time, these cache files can accumulate and take up several gigabytes.

  • Windows Temp Files: Use the Disk Cleanup tool (search for it in the Start menu) to safely remove these.
  • Browser Cache: Each web browser stores cache. You can clear this from within the browser’s settings under privacy or history.
  • Software Update Installers: Both Windows and Mac keep old installer packages. On Mac, they are often in the /Library/Updates folder. On Windows, the Disk Cleanup tool can remove them.

Clearing these periodically is a safe way to regain space without affecting your personal data.

Duplicate Files And Old Downloads

The Downloads folder is a common black hole for storage. It’s easy to forget about large ISO files, installer packages, or archived documents you downloaded once.

Make a habit of reviewing your Downloads folder. Sort files by size and date. Delete any old installers, PDFs, or videos you no longer need. Similarly, duplicate photos, videos, and documents can silently eat up space. Using a duplicate file finder tool can help you identify and remove these copies efficiently.

System Restore Points And Shadow Copies

Windows creates System Restore Points to help revert your system to a previous state. These points can consume a significant amount of space.

To manage them, search for “Create a restore point” in the Start menu. In the System Properties window, click on your drive and select “Configure.” You can adjust the maximum disk space usage for restore points or delete all restore points from this menu. This can instantly free up tens of gigabytes.

Step By Step Cleanup Guide

Once you’ve identified what’s using your storage, it’s time to clean it up. Follow this orderly process to ensure you remove files safely and effectively.

Step 1: Uninstall Unnecessary Applications

Large applications, especially games and creative suites, can use many gigabytes.

  1. On Windows: Go to Settings > Apps > Apps & features. Sort the list by size.
  2. Review the largest applications. Uninstall any you no longer use by clicking on them and selecting “Uninstall.”
  3. On Mac: Open the Applications folder in Finder. You can drag unwanted apps to the Trash. For a more thorough removal, use an app like AppCleaner to delete associated files.

Step 2: Clear Temporary Files And Caches

As mentioned earlier, this is low-hanging fruit.

  • Windows: Use the “Disk Cleanup” utility. Select your drive, and check boxes like “Temporary files,” “Delivery Optimization Files,” and “Windows Update Cleanup.”
  • Mac: You can use the built-in “Manage” storage option, which includes an “Empty Trash Automatically” feature and recommendations for clearing cache. For manual cleaning, apps like CleanMyMac X can be helpful but are not essential.

Step 3: Archive Or Delete Large Media Files

Videos, photos, and music libraries are often the biggest consumers of space.

Consider these options.

  • Move files to an external hard drive or a network-attached storage (NAS) device.
  • Upload photos and videos to a cloud service like Google Photos, iCloud, or OneDrive. Most offer free tiers with limited storage.
  • Review your media folders and delete blurry photos, duplicate videos, or music you never listen to.

Step 4: Manage Cloud Storage And Sync Folders

Services like OneDrive, Dropbox, and iCloud Drive can store files locally on your PC. You might have synced entire folders that you don’t need offline access to.

Check the settings of your cloud sync app. You can often choose to make files “online-only,” which removes the local copy but keeps them in the cloud. This frees up local space while keeping your files accessible when you’re connected to the internet.

Preventive Measures And Best Practices

Preventing storage from filling up is easier than constantly cleaning it. Adopt these habits to maintain healthy free space.

Regular Storage Audits

Schedule a monthly or quarterly check-up for your computer’s storage. Use the built-in Storage Settings or About This Mac tools to quickly see if any category is growing unexpectedly. Catching a space issue early makes it much easier to resolve.

Adopt Cloud And External Storage

Don’t treat your PC’s internal drive as your only storage location. Use cloud services for document syncing and photo backups. Use an external hard drive for large media archives and system backups. This strategy keeps your primary drive lean and fast.

Be Mindful Of Installations And Downloads

Pay attention during software installations. Often, bundled software or extra features are selected by default. Uncheck these to avoid installing unwanted programs that take up space. Similarly, after downloading a large file, ask yourself if you need to keep the local copy after you’ve used it.
