    Windows 11 does not provide a built-in duplicate-photo finder in the provided guidance, but duplicate pictures can be found and removed manually with File Explorer or managed from the Photos app.

    1. Open File Explorer from the taskbar.
    2. Go to the folder that stores the pictures, such as Pictures, Downloads, or another folder under This PC.
    3. Switch to View > Details so file information is easier to compare.
    4. Right-click in the folder and use Sort by > Size to group similar files together. Duplicate photos often have the same size and very similar names.
    5. Use the search box in File Explorer to search by:
      • file name
      • file type such as *.jpg, *.jpeg, or *.png
      • keywords if part of the name is known
    6. Review matching files carefully before deleting. Files with names like photo (1).jpg can indicate duplicates.
    7. Delete only the copies that are not needed.

    If the pictures appear inside the Photos app:

    1. Open Photos.
    2. Find the photo or folder.
    3. To stop a folder from appearing in Photos without deleting it from the PC, right-click the folder in the left navigation and remove it from Photos.
    4. To delete a photo stored in OneDrive from Photos, note that it is sent to the Windows Recycle Bin and also to the OneDrive recycle bin.
    5. If the photo is in an iCloud Photos synced folder, deleting it from Photos also deletes it from iCloud.

    If storage space is the goal, large photo folders can also be moved to an external USB drive or SD card:

    1. Connect the external drive.
    2. In File Explorer, select the photos.
    3. Select Cut.
    4. Open the external drive.
    5. Select Paste.

    Important: deleting files removes them from the device, and cloud-synced locations can also remove them from the cloud service. Check the folder location before deleting.

    Hello

    Windows 11 doesn't have built in feature to identify duplicate files.

    You can try what the AI answer suggested, but you can also use a free tool called "Microsoft PC Manager" https://pcmanager.microsoft.com/en-us

    Then use the Storage > Duplicate files option. It will scan for duplicate files and you can then review and decide what to do with them.

    Windows 11 has no built-in duplicate-photo finder, and the two methods usually suggested — sort by name, sort by size — both fail on photos specifically.

    Why they fail

    Camera and phone filenames repeat. IMG_4821.jpg from a 2022 import and IMG_4821.jpg from a 2024 import are two different photos that happen to share a name. Sorting by name groups them together and invites you to delete the wrong one.

    Size is worse. Two photos can both be exactly 4,096 KB and be completely unrelated images. Size narrows the candidate list; it never confirms anything.

    The check that actually answers the question

    Read the bytes and hash them. If two files produce the same SHA-256 digest they are identical — not similar, identical. A resized or re-encoded copy is a different file with a different hash, so this method will not propose deleting a photo you deliberately edited.

    Doing it efficiently is a three-pass job, cheapest first:

    1. Group by exact byte size. This alone eliminates almost everything.
    2. Hash the first 4 KB of whatever survives.
    3. Only for the files that still match, read the whole file and hash it.

    On a few hundred thousand photos this finishes in minutes instead of hours, and the output is a set of groups where every file in a group is byte-for-byte the same.

    Before you delete anything

    • Keep the copy in the folder you would look in first — Pictures\2024\ rather than Downloads.
    • Check whether something references the file: a Photos album, a Lightroom catalog, an attachment embedded in a project. Deleting it breaks that reference even though an identical copy still exists elsewhere.
    • Send files to the Recycle Bin rather than deleting permanently, then empty it a week later. That week is your entire safety margin.
    • Watch for hard links. Two names pointing at the same data look like duplicates but free zero bytes when removed. A tool that counts them is overstating how much space you will get back.

    On the Microsoft PC Manager suggestion above: Storage > Duplicate files does the size and hash comparison for you and is safe to try. Its limitation is coverage — it only looks where it scans. If your duplicates are on a second drive or an old backup folder, point a duplicate finder at those folders specifically instead of scanning C: and hoping it reaches them.
