Is it possible to recover deleted files from SD cards?

In general, there is still hope for recovery as long as the lost data is not overwritten. Let’s take deletion as an example to illustrate the data recovery idea briefly. If the SD card files are deleted, the files will not be shown in the file manager, but the files are not actually erased or wiped immediately.

Because the system just deletes the data from the file log and classifies the file's disk space as “free”. Before this "free" disk space is occupied by new data, the lost data is in a recoverable state.

How to get back deleted files from memory cards? The SD card files will be analyzed by data recovery software, and the lost files can be recovered.

How to recover deleted files from SD cards?

Several ways to recover deleted files from SD cards will be covered in this part.

Retrieve lost files from SD card using Windows File Recovery  

Another tool that could be utilized is an official tool released by Microsoft - Windows File Recovery. It's a command-line app, which could help users restore lost files in Windows 10 2004 and later.

But, using this tool is somewhat difficult without an intuitive interface, if you need an easier tool, please head over to the next part.

To use this tool, firstly, you need to figure out your File System, and what recovery modes and switches to use. More detailed info on these modes and switches can be found in the Windows File Recovery use guide.

To check your File System, go to “This PC” > right-click on the SD card drive > “Properties”.

Then choose a recovery mode according to your File System and files loss conditions.

File system Scenarios mode
NTFS Deleted recently Regular
NTFS Deleted for a while Extensive
NTFS Formatted disk Extensive
NTFS Corrupted disk Extensive
FAT and exFAT Any Extensive

And if you need to use switches to filter the scanning range, check this table.

Switches Meaning Supported mode(s)
/n Filter the scan range: scans for a specific file with its file name/path/type, etc. All
/y: Recover specific extension groups. Signature
/k Recovers system files. NTFS
Segment​​​​​
/u Recovers undeleted files, for example, from the Recycle Bin. NTFS
Segment

Now you could follow the steps below to start file recovery.

Step 1. Click "Get" to install Windows File Recovery in Microsoft Store.

get-windows-file-recovery

Step 2. Start Windows File Recovery, and input the command line. The Windows File Recovery command template goes like this:

winfr source-drive: destination-drive: [/mode] [/switches]

For example, if you need to recover word files that you have deleted for a while from F: drive to D: drive, then you need to choose Extensive mode (Non-NTFS could only utilize Signature mode). Unfortunately, the Signature mode could not be used with the "/n" filter.

Then the command will go like this:

winfr: F: D: /signature

winfr-sd-card-signature

Step 3. Click "y" to continue. When finished, a folder named "Recovery_date and time" will be automatically created.
