Opening F4F files

Did your computer fail to open a F4F file? We explain what F4F files are and recommend software that we know can open or convert your F4F files.

What is a F4F file?

The .f4f file extension is used for a proprietary data file format that was created by Adobe Systems, Inc. These F4F files are also called Adobe HTTP Dynamic Streaming segment files. Data files with the .f4f extension are generated by the File Packager applet, which is part of the Adobe HTTP Dynamic Streaming service.

The Adobe HPPT Dynamic Streaming service is part of Adobe Media Server. This software is used for the distribution of multimedia content through HTTP connections.

Segments of multimedia content are stored in these F4F files. These .f4f files are also known as Flash MP4 fragments.

These .f4f files are not meant to be opened by multimedia players and video editing applications. It's recommended to leave these F4F files alone, in order for Adobe Media Server and the Adobe HTTP Dynamic Streaming service to continue working properly.

Software that will open, convert or fix F4F files

Unfortunately we have not received enough suggestions for software that can open F4F files yet.

Try a universal file viewer

I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
