What are Junk Files?

Your hard disk is the storage device that holds the entire Windows operating system and all of your important files and data.

Through normal use of your computer, your hard disk will become cluttered with hundreds or even thousands of Junk Files. These junk files are created by Windows and other programs that writes temporary files, during installation and when running, to your hard disk which they need to do in order to work.

remove junk files 

The problem is often that these junk files are not removed from your hard disk, even after they are no longer needed, and waste important  disk space for your computer to run optimal.

A hard drive has a limited amount of space. If you run out of hard drive space, your computer may lockup, crash, or even fail to start-up.

The more files you have on your hard drive, the more time it can take to access files while using the computer, the more data you have on your hard drive, the performance is much slower.

Removing the garbage files from your system can regain megabytes or even gigabytes of valuable disk space on your hard drive. This will give you more hard drive space for new programs as well as data files like pictures, movies or other important files and helps avoid possible computer issues caused by low disk space.

FULL-DISKfighter easily allows you to remove these unwanted junk files to instantly free up hard disk space.

    I have faced the same problem. It is very dangerous for our system sometimes it may cause the crash of the hard disk.

  2. I completely agree…. I have this CCLEANER software which i use to remove unwanted junk files…. & believe me the Computer starts working faster after the clean up…. I have incorporated the use of c-cleaner in my daily routine… due to which temporary n junk files are destroyed…

  3. Kristoffer says:

    Nice post! Really got my brain working. And by the way, thanks a lot for the “Fighter”-series – they’re great!

  4. Pas says:

    By also clearing out a lot of junk files and clearing up your memory, doesn’t that also make your computer run a lot faster and smoother?

  5. There are many techniques that can make your computer faster, the one you mention is just one of them…

  6. Mike says:

    Yes, clearing out certain files might make your PC run faster but the sad fact is over time the Registry gets so hosed up with junk that it can also affect performance.

    The other thing is when you uninstall programs most of the time files get left behind and after a couple of years this just adds to the problem.

    That is exactly why me and the hubby recently switched over to Macs and so far we are loving them. No regrets at all!


  8. Steve says:

    This junk files are very danger..I had lot of junk files on my computer and somebody HACKED my Computer.

    These temporary files are created automatically in your computer and should be removed from your computer automatically as well. The software which generates the Temp Files should remove those files also as soon you close that software for example if you open Ms-Word and works on a document then you will see that Ms-word has created a temp file as well just for a backup and when you close Ms-Word, the temp files will also be removed automatically. But not all softwares follows the same procedure. It can be because of bad software that creates temp files or because of improper shutdown, System crashes or hanging problems that these temp files remains in your system and starts creating the problems

    All of your personal information get saved in these files when ever you fills a form on internet or do an activity similar to it. After filing such forms, the data remains saved in your computer and these websites fetch the data from your computer secretly and use it for their own purpose

    Cheers. Those f*ckin’ junk files kills me!!

  11. klaus says:

    thanks a lot for the “Fighter”-series. i like the whole serie

  12. PC says:


    I’m thinking of using PC Maximizer 3.0, it says it will delete junk files, what I won’t to know is that will it delete important files like photos, documents, games etc? 🙂

  13. Kim Falkner says:

    Hi PC,

    Thank you for your comment. For removing junk files on a PC we would however recommend our very own FULL-DISKfighter: It will remove junk files and duplicate photos if you prefer that.

  14. Linda says:

    Beware of buying Software over internet…read the terms. I was going to buy PCMatic until I read the terms and discovered that they automatically roll over your purchase the following year unless they receive written information from you not to automatically charge your card whatever amt. they like the following year. This information must be submitted in writing at least 15 days before the end of your original term. That is totally unacceptable to me. But it taught me a valuable lesson. I had gotten in the habit of just checking the I Agree Box without reading the terms because the writing always was so small and also plain lazyiness on my part. Thank goodness I did read it & will continue to do so from now on.

  15. Price says:

    I agree with Debra. Why do the computer and program makers not have a built-in facility to delete the temporary “junk” files and so-called registry problems they deliberately when the program is being closed. It seems to me that the industry is hell-bent on protecting its future. It forces us to buy, buy, buy new software to protect us against junk files and other pervasive stuff which if and with honesty the makers could avoid. Eventually we are “forced” to buy a new and larger computer. But then we have to buy all the programs again. Then the cycle starts all over again with new junk files and other types. Little wonder that the computer industry is the one that makes the highest profits. And what was wrong with the older programs that made us want to buy the later versions that are no better than the older ones?

  16. Mertsi says:

    Just removed OVER 30GB of junk files. Feels like I just bought a new computer!

  17. Kaushal Sehgal says:

    Its vital for us and for our computer as well to get ride of these kind of files else it will cause you data crash or hard drive crash or both at the same time.

  18. Peter Ridgers says:

    Why, why, why do so many people keep all their old digital photo’s on their hard drive. I have just erased 60GB of old photo’s from a friend’s pc – that was over 15,000 pictures. At ten seconds per picture it would take nearly two days just to scan them all. They all had the standard camera-generated name so he couldn’t even meaningfully search for a particular photo. For the average person, take your holiday snaps, show them to your friends. Store very special ones and throw the rest away!!!

  19. Mie Pedersen says:

    Agree – if you don’t want to keep the photos you should delete them. However, it’s this ‘clean-up’ that people rarely take the time to do before they’re in over their heads. Personally, I import my photos to a special folder dedicated to the given event. That way I can easily find the pictures and/or delete them if I want.

  20. Karen says:

    R their any free & safe ones & if not free then cheap?

  26. akshay singh says:

    I used yellow booster for cleaning my phones junk file and boost ram. The memory of junk files is 6 gb approximately. After cleaning junk files all of a sudden i lost about 1500 images.please help me what to do now.

  27. Christina Urban Sørensen says:

    Dear Akshay Singh,

    Im sorry to hear that you’ve lost all your images from your phone.
    I would recommend you to contact Yellow Booster yourself and ask if the app can restore the deleted junk files:

    Also – I would recommend you to save images and maybe your contactlist in a cloud blackup, so if this were to happen again, or if you should loose your phone, the images wouldn’t be gone.
    There exists many providers of cloud services, so you can start by searching for “cloud” where you download and purchase apps on your phone. (Google Play or App Store)

    Best Regards

    Do not worry if you want to remove the blocked files or too long path files from your system, here I suggest a smooth way. Use “Long path tool” software and keep yourself cool.

  36. SC says:

    I do believe all the ideas you’ve offered in your post.
    They’re really convincing and will certainly work. Still, the posts are too brief for beginners.
    May just you please extend them a bit from subsequent time?
    Thank you for the post.

    if I stack my junk files on a flash drive and then dump them in another pc will this harm it

  38. Isabella Shepherd says:

    I convert videos into a lot of JPEGS sometimes working with tens of thousands of images at any given time. What I need is something that reduces the risk of my hard drive and my RAM being so fragmented I will spend more money fixing it than not. Any tips and suggestions will be greatly appreciated. I don’t have thousands upon thousands to fix everything if it goes. I don’t mind paying for software that does deep cleans and actually removed the junk folders/files.

  39. Michael says:

    I use the software Krojam Cleaner and I recommend you try it. It is a powerful tool proven to be effective for removing unnecessary junk files.
