If you use a new Windows computer, your PC will most likely be free of redundant duplicate files. If, on the other hand, you have used your PC for quite some time now (years maybe), you most definitely have a couple of files that have been duplicated on your device. Having duplicated files on your device eats up your PC’s internal storage space (without your knowledge), leaving little space for important program files to run efficiently.
Why you have Duplicate Files on your PC
Duplication of files on Windows PC could be as a result of:
- User: Yes, it’s possible you put them there. Perhaps you downloaded an image of your friend twice or you clicked the download button twice when you tried to save a file from a webpage. Sometimes, users also assign a file the same name they’ve previously given a dissimilar file/document. These things happen. It could be unintentional but let’s face it: you are the reason you have duplicate files on your PC. And it isn’t a bad thing. We’ve all done it — at least once.
- Automatic OS Build-up: Sometimes it’s your PC. They (Windows PCs) build-up redundant duplicate files and saves them up in your hard disk. To protect your PC (and files) against certain types of malware, the Windows OS automatically creates a duplicate of some files and saves them in a private place on your computer. Windows does this so that the files can be easily restored/replaced should a virus/malware corrupt/delete them.
- Software Programs: Some programs you have on your PC could also create duplicate files. This sometimes happens when they are being updated to a newer version; certain programs leave old redundant duplicate files behind in your PC.
If you have noticed that your PC’s storage space is low, and you haven’t been storing a lot of data on it, you might want to scan your computer for duplicate files and delete them (or a copy, preferably).
