What is an EFC file

EFC files mostly belong to Samsung Photo Editor. The EFC file is an encrypted container file.: It is used to package data such as photos and other sensitive content. In many cases, these files are created by Samsung Photo Editor to store photo frame images. At other times, they are used as secure containers for image data, like those seen with Adobe Photoshop Camera Raw files, or even for encrypted spreadsheet data.
  • Samsung Photo Frame Images: These files hold photos intended for digital photo frames. The Samsung Photo Editor creates these files, and more details can be found on the Samsung website.
  • Encrypted File Containers: Other EFC files serve as encrypted containers. They might include a standard JPEG format inside to hide data such as Camera Raw images or even spreadsheet content.
  • Always open an EFC file with the original software that created it to correctly handle its encryption and formatting.
    FilExt.com tip: Do not change the file extension or use generic image viewers, as the encryption may prevent proper decoding.
