Over time, using an SD card may accumulate duplicate files, including photos and videos. These duplicate files on the SD card will slow down performance. This post shows detailed steps to find and delete duplicate files on SD card using File Explorer and MiniTool Partition Wizard.

SD cards are essential for expanding storage space in cameras, smartphones, drones, and portable devices. However, frequent transfers, backups, and downloads inevitably lead to duplicate files (photos, videos, documents, and audio clips).

Duplicate files typically form when:

  • Files are transferred multiple times between devices.
  • Older versions are not overwritten when backing up the SD card.
  • The same file is downloaded or saved with slightly different filenames, such as “IMG_123.jpg” and “IMG_123(1).jpg”.
  • Cloud storage (OneDrive, Google Drive) is synced with the SD card.

These duplicate files consume storage space, slow down access, and complicate file management.

Therefore, regularly cleaning up duplicate files is crucial for maintaining optimal performance and preventing storage space from becoming depleted.

This guide explores two effective methods for deleting duplicate files on your SD card in Windows 10/11. With manual deletion and an advanced automation tool, you can optimize your storage space without losing data.

Method 1. Delete Duplicate Files on SD Card Manually

This method is best for a small number of files because they allow you to easily spot duplicate files by name or size. Follow these steps for safe manual deletion:

Step 1. Access the SD card in your computer.

  1. Insert your SD card into your computer’s card reader. If your PC doesn’t have a built-in reader, use an external card reader.
  2. Press the Windows + E key on your keyboard to open File Explorer.
  3. In the left pane, click This PC.
  4. In the right pane, locate your SD card under Devices and drives. Double-click to open it.

Step 2. Change the View to Details to see duplicate files easily. This will display file properties such as size, date modification, and type.

  • For Windows 10, go to the View tab at the top of the File Explorer window. In the Layout section, select Details.
  • For Windows 11, click View at the top toolbar, and then select Details from the drop-down menu.

Step 3. Sort the duplicate files by clicking the Name, Date modified, or Size column. Sorting makes it easier to spot potential duplicates, which often have similar names (e.g., “IMG_123.jpg” and “IMG_123 (Copy).jpg”) or identical sizes.

  • Click the Name column to group identical or similar filenames.
  • Click the Date modified column to identify duplicate files resulting from recent duplicate transfers.
  • Click the Size column to sort files by size. Duplicates are often the same size.

You can also use the search bar to filter by file type (e.g., .jpg, .docx, .pdf, .mp4), size, or name.

Tips:
For photos or videos, switch to View > Large Icons to scan thumbnails. This makes it easier to spot duplicates at a glance.

Step 4. Identify and delete duplicates.

  1. Manually review the files to confirm which ones are duplicates.
  2. Right-click the duplicate files and choose Delete. To select multiple non-consecutive files, hold down the Ctrl key while clicking on them.
Tips:
Only empty the Recycle Bin after confirming that no original files have been accidentally deleted.

Delete Duplicate Files on SD Card FAQ

1. Does deleting duplicate files free up my SD card?
Yes, deleting duplicate files can indeed free up space on your SD card. After deleting redundant copies of photos, videos, or documents, you can store more original content.
2. Can I recover duplicate files removed from my SD card?
Yes, duplicate files deleted from an SD card can usually be recovered, except by using software to permanently delete them. Since deletion usually only removes the file entry, the data itself is not lost until it is overwritten.
3. Why do deleted files keep coming back on SD cards?
Files reappearing on your SD card after deletion usually mean the card is corrupted, write-protected (read-only), infected by malware, or an app is restoring them.
4. How do I prevent duplicates from forming?
Here are some tips:
1. Use consistent file-naming conventions (e.g., “2026-01-Vacation-IMG123.jpg”).
2. Use cloud storage sync tools with “replace duplicates” enabled.

Bottom Line

Deleting duplicate files from SD cards in Windows can free up storage space, provide faster access times, and organize data.

For small-scale cleanups, manual deletion suffices. For large file detection, third-party software like MiniTool Partition Wizard offers efficiency and safety.
