What is ORF?

The ORF file format represents a raw image captured by an Olympus digital camera. Unlike JPEG files, ORF files maintain the original image data without losing quality due to compression. This means essential attributes like color, saturation, and contrast are preserved exactly as captured by the camera’s sensor.


In contrast, JPEG files tend to degrade in quality with each subsequent opening, limiting their editing possibilities. ORF files boast a bit depth of 12 or more per pixel, whereas JPEGs are limited to 8 bits.

However, it’s important to note that viewing ORF files on your computer may require specialized software. Standard image-viewing applications might be unable to handle this specific file format.


Is it possible to perform ORF file recovery?

The potential for ORF file recovery depends on how the data was lost. Here’re some of the causes of data loss. 

Accidental Deletion:

If you accidentally deleted ORF files from SD cards, these don’t vanish immediately. The memory occupied by the deleted data becomes available for new information.

Recovery is possible as long as the deleted file hasn’t been overwritten. To maximize the chances of recovering deleted ORF files, it's crucial to cease using the device immediately to prevent overwriting.

◢ Formatting:

Quick Format doesn’t erase your data; it merely creates a new file system for your operating system. In this case, data can still be recovered if you stop using the memory device promptly to prevent ORF file overwriting.

But Full Format can replace the data. Please get more details on Quick Format VS Full Format if needed.

◢ Corruption:

Logical corruption of storage media can render it unusable. Your storage device containing the ORF files might get corrupted due to factors like viruses, abrupt ejection, or power outages.

How to recover deleted ORF files without backups?

Since deletion stands out as the prevailing circumstance for data loss, let’s describe how to recover deleted ORF files.

Foresighted users who’ve created regular backups are not concerned because they can get their desired ORF files from backups. Without backups, only reliable data recovery software like MyRecover can help you recover deleted & lost ORF files from Olympus camera SD cards and computer hard drives.

If you permanently deleted ORF files from your Windows computer during editing, it’s also possible to recover permanently deleted ORF files via MyRecover.


  • After SD card recovery, you’re supposed to save your retrieved ORF files in a new path instead of the original Olympus camera SD card.

Step 2. MyRecover will automatically scan your Olympus camera SD card and search all the recoverable files.

You can preview/filter specific files according to Documents Type, Name, Path, or Date.

  • Name: Type the relevant filenames in the search bar to quickly locate your desired deleted/lost files.
  • Date modified: Set a customized date (today, yesterday, last 7 or 30 days, etc.)
  • Size: Filter the file size (<128KB, 128KB~1MB, 1MB~512MB, etc.)


Step 3. Under the Other Missing Files Folder, select your needed ORF files. Then click the “Recover x files” button.


After recovery, go to your designated saved path to see if your selected ORF image has been recovered or not. Its filename of the recovered folder is the original saved drive + date.
