What is an FFF file?

FFF files mostly belong to Phocus by Hasselblad. An FFF file is mainly used to store a RAW image encoded in Flexible File Format (also known as Hasselblad 3F or Imacon 3F format). The image stored in an FFF file is usually captured by a Hasselblad or Imacon digital camera or scanner. FFF format is based on TIFF format; it stores high quality, uncompressed graphics data exactly as captured by the CCD sensor on a digital imaging device. Phocus is Hasselblad's default program for viewing and retouching FFF images. Preview, Photoshop, and PaintShop can also open and export FFF images. Pegasus Mail email management software uses a form fact saved in an FFF file. Additional information about each form fact in a Pegasus Mail installation is saved in the fff.txt file in the WinPMail program directory or its "Resource" sub directory. Simplify3D 3D model slicing and printing software saves slicer profiles (settings) in an FFF file.

How do you open FFF files?

You need a suitable software like Phocus to open an FFF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FFF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FFF file directly in the browser:. Just drag the file onto this browser window and drop it.

FFF file format details:

A file format defines how the data in the file is structured. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the FFF files is as follows:

The file type with the extension 'FFF' covers different formats for different programs. The two most popular formats are as follows:

All other FFF files (30%) have no uniform format, often e.g. Gravis UltraSound PnP InterWave patch, EXE, TIFF and DOC. These files are often connected to pmfby, data, sugarcane or entry. Drag & drop your file here to see the file format and a preview of your FFF file!
