Why do duplicate video files pile up on your PC?
Duplicate video files can quickly accumulate on your PC, hogging valuable storage space. These redundant files are often unintentionally created through various means. First, let's delve into why duplicate video files appear on your PC and where they typically hide on your hard disk.
▶ Why do duplicate video files occur?
Duplicate video files can be attributed to several factors:
Multiple downloads: Sometimes, you may unknowingly download the same video more than once, especially when using different browsers or download managers.
File transfers: When you move video files between devices, duplicates can emerge if you're not meticulous in organizing and managing your data.
Incomplete downloads: Interrupted downloads can leave behind partial video files that get duplicated when you attempt to download the same content again.
▶ Where are duplicate video files stored?
Just like normal files, duplicate video files won’t be stored in a signed location. They can spread on your drive. But, usually, these files tend to hide in various corners of your hard disk:
Download folders: Duplicates often linger in your download folders, especially if you frequently download videos from the internet.
Media libraries: Video libraries in media players or editing software can also harbor duplicates, as you may inadvertently import the same video multiple times.
Backup drives: If you back up your videos to external drives, duplicates can accumulate there as well, consuming precious backup space.
▶ The menace of duplicate video files
Duplicate video files may seem harmless, but they can pose several issues:
Wasted storage space: Redundant video files can take up significant storage space, leaving you with less room for new content or important data.
Performance degradation: A cluttered hard disk with numerous duplicates can slow down your PC's performance, leading to lag and sluggishness.
Difficulty in organizing: Managing large collections of duplicate videos can be time-consuming and confusing, making it challenging to find the content you want.
Thus, to keep your computer in a nice status, we suggest you clean your duplicate files and video files regularly to minimize the menace of these files.
How to search and remove duplicate video files via Windows File Explorer
Windows File Explorer provides a built-in tool that allows you to search for and remove duplicate video files with ease.
Step 1. Press Windows + E on your keyboard to open File Explorer. Go to the directory or drive where you suspect duplicate video files may be stored.
Step 2. In the top-right corner, you'll find a search bar. Type the following command and press Enter: ext:mp4 OR ext:mov OR ext:avi OR ext:mkv
This command tells Windows to search for video files with common extensions.
Step 3. After the search is complete, click on the "Size" column header to sort the files by size. This will help you identify duplicates that are often the same size.
Step 4. Carefully review the search results and select duplicate files by holding down Ctrl and clicking on each one. Once selected, right-click and choose "Delete" to remove them.
Indeed, Windows File Explorer can find and remove duplicate video files, but, the process will perform extremely slowly. The task will take up many resources on your computer but you’re not allowed to pause if you have to give priority to other important jobs. What’s more, the search process is often interrupted during PC usage.
