What Is a PEF File?

PEF (Pentax Electronic Format) is a high-quality raw image captured by Pentax Digital Cameras with zero compression & minimal processing. So these files usually include a large amount of image data that a basic image editor cannot process.

Similar to other raw images, .pef files are valuable to photographers who can further develop the photos to give them another look. They can also be converted to other formats, such as .jpg, .jpeg, .png, .bmp, etc.

Why Do You Lose Your PEF Files?

In fact, there are many possible reasons of PEF file deletion. The following are some of the common reasons:

• Accidental deletion, such as click the “Delete All” tab on Pentax Camera.
• Formatting error, you need to format the disk before you can use it, for example.
• file system damage.
• Abrupt removal of storage device.
• Interruption during the file transfer process.
• Storage device corruption due to virus attack, improper shutdown, etc.

Is PEF File Recovery Possible?

When you delete a PEF file, it might not be removed completely from the device or computer. Instead, the occupied space will be marked as “free” for new data. This means your PEF files are recoverable before the old data is overwritten.

So please stop using your storage device or computer immediately after data loss. Don’t add new data to them. In addition, act promptly and start the data recovery process as soon as possible. The success rate gradually decreases with time.

In addition, the success rate varies in different data loss scenarios. For example, the quick format method will not overwrite old data but the full format will, making data recovery more challenging.
