If your hard drive does not have enough space then it might be because of a number of duplicate files. Same photos, videos, documents, music files, download files can be saved in different folders and you are not aware of this. Duplicate files take extra space and make it difficult to find the right file
You have two options to check duplicate files on a hard drive. One is the manual method through file explorer and the other one is to use duplicate file removal. If you have big data in your hard drive, then using a duplicate file finder is the best way to find duplicate files. For a small amount of data on a hard drive file explorer can be useful but it takes time.
In this guide you will learn how to check duplicate files on a hard drive manually and how to use a dedicated tool for identifying duplicate files.
What Are Duplicate Files on a Hard Drive?
A duplicate file is basically a file with multiple copies which are stored on a hard drive in different locations and the name of the file can be the same or different. Let us understand with an example
- Family-photo.jpg
- Family- photo (1).jpg
- Copy of family-photo.jpg
You cannot confirm just by seeing their file names that they are duplicate files. There might be a chance that the name of the file is the same but it has different content.
Here duplicate file scanners and removers play an important role if you want to save your time. The tool will help you find duplicate files after scanning the hard drive automatically and show groups of duplicate files.
Why Check Duplicate Files on a Hard Drive?
Duplicate files are not always unnecessary. Sometimes we make backups for personal use or official purposes. Problems happen when there are too many duplicate files, by checking duplicate files you can:
- Maintain free storage in hard drives
- Remove large unnecessary files from hard drive
- Organize photos and documents in a proper way
- Clean old project folders
- Reduce confusion between similar files
- Locate easily important files in future
How to Check Duplicate Files on Hard Drive Manually
If you have only one or two folders then you should not need special software. You can search through Windows File Explorer and sort out those files based on different properties.
Step1 open file explorer
Open file explorer and select hard drive folder which you want to check and if you want to check complete hard drive then you must select this PC
Step 2 change to Details View
Select details view in file explore with this you can see clearly important information like
- Name
- Date modified
- Type
- Size
Windows File Explorer allows you to view and organize file in different ways.
Step 3 Sort Files by Name
Select file according to name with this you notice that some files like
- docx
- Document (1).docx
- Document copy.docx
You should not delete files after seeing similar names, you should verify content or purpose of the file.
Step 4 Compare File Size
Now you should compare suspect file size, if two files have different sizes then there may be a chance they are not duplicate files but If two files have the same name and same size they may be duplicate files. Comparing file names and sizes can help you identify duplicate files before deleting them.
Step 5 Check the File Locations
Now you need to check file location for example
D:\Photos\Holiday.jpg
Or
D:\Backup\Holiday.jpg
Both files are the same but the second file can be stored intentionally for backups, that is why you need to understand the purpose of the folder before deleting them.
Why Manual Checking Is Not Enough for a Large Hard Drive
Manual checking can be useful for small folders but when you check a large hard drive then it takes lots of time. Duplicate files do not always have
- Same name
- Not stored in same folder
- Same date
- No “copy” or “duplicate” label
Even after renaming the file, its content can remain the same. If you have thousands of files you must use a dedicated duplicate file finder and remover tool.
How to Find Duplicate Files Using a Duplicate File Finder
A SysTools duplicate file finder and remover tool helps you identify duplicate files on hard drives in a short time. Here are some steps you must follow
Step 1 Select the Hard Drive
You need to open a duplicate file finder tool and select the hard drive which you want to check. You can choose folder instead of scanning complete drive for example
- Downloads
- Pictures
- Videos
- Documents
- Desktop
- External hard drive
If you want to check only the pictures folder in the hard drive then you can select only pictures.
Step 2 Start the Scan
Start scanning that folder and scanning time depends on
- Total number of files
- File sizes
- Hard drive speed
- Selected folder
- Comparison method
Step 3 Let the Tool Compare Potential Matches
The tool starts scanning files in hard drive
- The tool checks file size
- File name
- Comparing file contents
Then the tool shows exact duplicate files in your hard drive and this process does not take long.
Step 4 Review the Duplicate Groups
This is a very important step because you should not blindly delete folders from the hard drive. You should check and review
- File name
- File size
- File location
- Date modified
- File type
- Preview if option available
Then you can decide which file you want to keep.
Step 5 Remove the Selected Files
Delete the selected files from the hard drive permanently and this helps you free up space on the hard drive and keep files better organized.
