6 Ways to Free Up Space on Your Windows Computer

Joel Lee 26-08-2013

Clutter can be a big downer on productivity, whether it’s your workstation, your home, or your computer. Entropy is the reason why clutter builds up over time, and entropy takes many forms in the context of computers. Files get lost, programs go unused, and little by little various nooks and crannies in your computer are taken up by stray bits of data. Suddenly, your once spacious hard drive is packed with useless things 6 Tips to Free Up Disk Space in Windows 10 Even a terabyte of storage space is quickly filled with media files. Here we'll show you how to easily free up gigabytes of disk space in Windows 10 by removing redundant system files. Read More and you have to clean it up. But how?


It’s not enough to delete things left and right. You need to find the big space hogs, identify which ones are worth deleting, and make sure you aren’t causing harm to your system in the process. Fortunately, there are a few methods you can use to maximize space cleaning on your Windows computer. Open up your technical toolbox and add these to your repertoire because they’ll come in handy every few months during your routine clean.

1. Analyze Disk Space

The first thing you want to do is analyze your disks Automatically Free Up Disk Space with Windows 10 Storage Sense When you're running out of disk space, what do you do? Windows 10 has a feature called Storage Sense that can help you clear those space hogs. We show you how to set it up. Read More to see which items are taking up the most space and where they’re located. The reasoning for this is simple: if you want to clean up space as much space as you can in the shortest amount of time, the quickest way is to get rid of big sized items.

But the disk analyzer is also useful for finding hidden or forgotten files. Remember those files you downloaded months ago yet couldn’t find where they’d gone? Or maybe you stockpiled a bunch of files that were useful to you a year ago but now mean nothing? Well, they’ve been taking up space all this time. A disk analyzer will tell you that they exist and you can then go ahead and delete them.


For this, I use the program called WinDirStat, which stands for Windows Directory Statistics. It scans your entire system and organizes everything into an easy-to-navigate tree that shows you which folders take up the most space Visualize your Hard Drive Usage with WinDirStat Read More and what items are taking up that space. Hard drive visualization tools WizTree Can Help You Find What Is Hogging Your Disk Space [Windows] Some users prefer visuals and need charts and graphs, or others need as much numerical data as possible, and then some of us just want the information on our screen as fast as we can... Read More like WinDirStat or WizTree make it even easier to see where the big problems lie. I highly recommend it.


2. Clear Temporary Files

Temporary files are exactly what their name implies: files that temporarily useful. This means you can go ahead and delete them without much fear of breaking any critical procedures on your system. Most temporary files are used during program installations (having to unpack all of that data before moving it onto your system) and by browsers (for cache reasons), so it’s pretty safe.

On the topic of browsers, you may want to check out Browser Cleaner. On the one hand, every browser has a built-in option for deleting temporary data 7 Hidden Windows Caches & How to Clear Them Cached files can take up a lot of bytes. While dedicated tools can help you free up disk space, they might not clear it all. We show you how to manually release storage space. Read More like history, downloads, cache, cookies, etc. But with Browser Cleaner, you can clean out more than one browser at a time and all it takes is one button. On top of that, Browser Cleaner can clean application-related temporary data, such as IM logs, program caches, etc. Very easy, very fast, and very convenient.

3. Remove Duplicate Files

I don’t know about you, but there have been many times when I’ve downloaded a file and moved it off to some place for safe keeping only to forget where I’ve put it. Fastforward a few days later and I don’t see the file anywhere, so I download a new copy of it. If this happens a few times – especially if the file is a big size thing, such as the installation file for a large program – then it can really eat up valuable space.



Fortunately, there are a number of tools designed to remove duplicate files Delete Duplicate Files Quickly With These Tools One of the fastest ways to clog up your hard drive is to store duplicate files. Most of the time, you probably aren’t even aware that you have duplicate files. They come from a variety... Read More in a flash. Check them out, find one that looks like it interests you, download it and give it a go. Deleting duplicate files is a great way to free up lost space, and the best part is that you don’t actually lose any content in the process since they were duplicates. I’m personally favorable towards dupeGuru.

4. Wipe Unused Feature Space

Did you know that some of the features in Windows, like System Restore and Hibernation, require hard drive space to operate? That’s right. A lot of your hard drive might be eaten up by space that’s been reserved for these features – even if those features haven’t been used in ages.

There are two ways to tweak System Restore: reduce the amount of reserved space OR delete past System Restore points. We’ve answered how to delete system restore points before, so look there for specific directions on how to do that. Just know that you can save on gigabytes of data with this depending on how much of your computer settings are dedicated to System Restore.



Hibernation, on the other hand, is a system feature that lets you save the state of your computer before you “shut it down,” then restores that state when you “turn it back on.” All of this information is saved to the hibernation system file, which takes up a lot of space. If you disable hibernation and delete that file, you can reclaim that space. For specific instructions, How-To Geek has a post on deleting hiberfil.sys.

Note: Do these system alterations at your own risk. MakeUseOf claims no responsibility if you damage your system in any way. If you aren’t sure of what you’re doing, don’t do it!

5. Upload to Cloud Storage

One of the newer advancements in technology has been the cloud. More importantly, cloud storage Dropbox vs. Google Drive vs. OneDrive: Which Cloud Storage Is Best for You?

If you don’t want anyone – and I mean anyone – reading your data, then don’t upload it to the cloud. Otherwise, feel free to use cloud storage as extended storage or even just as a backup.

6. Uninstall Programs

Of course, don’t forget that you can uninstall programs to free up space. If you have any programs that you haven’t run in years, go ahead and uninstall them, but make sure you have some way of reinstalling them if you ever need them. For web downloaded stuff, don’t fret, but I’m talking about CDs and DVDs for paid software – make sure you still have those before you wipe them from your drive.

While the Windows default uninstaller works fine for most programs, you can try a third party tool like GlarySoft’s Absolute Uninstaller to completely remove all traces of installed software.

    Decent article, though pretty confident the best tool for tracking down which folders or files are the culprits of hogging storage is Disk Space Fan. It uses what's called a Starburst chart to visualise the biggest folders and the second you see it, you'll see why bar charts and numbers are pants.

    I would highly recommend using MalwareFox software. All you have to do is install the software and it will scan, detect and fix all the files and data which are affected by malware.

    To free up WINSXS space after a service pack install, run the following from an administrator command prompt:

    DISM /online /Cleanup-Image /SpSuperseded

    NOTE: You will not be able to uninstall the SP after running this.

    How about the default methods like performing Disk Cleanup and Disk Defragmentation at regular intervals?

    • Joel Lee
      August 27, 2013 at 9:59 pm

      Good point on the Disk Cleanup, though deleting Temp Files is probably the biggest reclamation of space using Disk Cleanup. As for Disk Defrag, I don't think it actually frees up any space.

      • Pratyush R
        August 27, 2013 at 10:35 pm

        Disk Defrag does cleans up disk space. I've tried it many times for defragmenting my C: (Win) .. let the cycles of Defragment disk run once, until all the pass are complete, it alligns the fragments and around 2-10% of disk space frees up. #TryItOnce

        #Note: Dont ever defrag the System Reserved (Disk space)

      • Pratyush R
        August 27, 2013 at 10:38 pm

        * doesnt cleans up but it actually frees up the unallocated disk space.

      • Pratyush R
        August 27, 2013 at 10:46 pm

        do correct me if I'm wrong, about defrag freeing up disk space.

      I believe this website also caters to not so computer savvy folks, so these things need to be reposted from time to time so they can be seen. It is even helpful for me just to see if there is anything new or to refresh my memory on certain things. Usually we just search for something when we need it though if we can't remember.

      Any limited scope publication will have everyday articles that will repeat. People need to be reminded of the techniques, and new readers are always coming along who will be hearing this stuff for the first time. Even newspapers, which don't have a limited focus, will have content that is a rehash of stories done previously...for the same reasons.

    In Linux Temporary files are deleted automatically and please tell to everyone how to make files stay at cloud and deleted from computer because if you delete something from dropbox folder,the file will delete from cloud too.

      I believe what you're looking for is either "desyncing" or "disabling cache" for the cloud, but I'm not 100% sure on that.
