Why SD card files can be recovered? The principles of file recovery

Deleting a file from an SD card does not mean that the file is actually erased. In fact, the space of the SD card to store the file can be used for the file transfer process, such as copying, deleting, and formatting. These operations only simply change the storage location of the file to a writable state, which do not eliminate it completely.
That is, although we cannot open the file with the appropriate path on the operating system, the file still exists in the SD card in digital form. However, once the original storage location of the file saves new file, the files in that location of the SD card will be overwritten and corrupted and finally could lead to recovery failure. Even if this part of the file is recovered by technical means, you can retrieve files that are corrupted and cannot be opened at most.

Therefore, as long as the user does not perform a secondary write to cover the new file after losing the file, it is likely that the lost file can be recovered completely. So how can you safely and efficiently recover SD card files? Please refer to the following two methods.

Method 1: Use Windows “Previous Versions” function to recover the lost files

If you’re looking for the methods of recovering the lost files from Windows 10/8/7, you can try the “Previous Versions” feature that comes with Windows for file rescue. This feature enables users to recover SD card files that have been accidentally deleted, formatted, or overwritten with the help of a backup file history and a restore point. Although most users don’t realize the existence of this feature, it can be very useful in finding back the lost data.
1. Navigate to the folder where the lost files were recovered.
2. Right-click the empty area of the folder, and then select “Properties”.

3. Go to the “Previous Versions” TAB. Select the latest version from here, click the “Restore” and save the replaced file or deleted file to complete the save operation of the original file.

Limitation: Windows uses the “Previous Versions” function, which requires users to back up regularly in advance, but most users don’t use them actively, so it is often impossible to use this function for recover. If there is no previous version available for recover, you can refer to the method below to retrieve the lost files that are not backed up.
