Opening an FSR File

The FSR file type is primarily associated with Flight Simulator X.

FSR	File extension: FSR
	File type:	simulation recording file

What is an FSR file?

FSR files mostly belong to Flight Simulator X. FSR files are recording files created by Flight Simulator X that capture flight simulation sessions. Unlike standard multimedia files, they store simulation data rather than continuous video.
These files record details of a virtual flight, including parameters like flight path, control inputs, and system events. This structured data is used to replay or analyze a flight session within the simulation environment.
Key points compiled by FilExt.com include:

Purpose: Store simulation events for accurate session replay.

Usage: Open with Flight Simulator X or a compatible viewer; standard media players will not work.

Integration: Often associated with the FS One Recorder tool for managing these recordings.

Format: A proprietary recording format optimized for simulation data, not for direct video display.

How to open FSR files

You need a suitable software like Flight Simulator X to open an FSR 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 FSR file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FSR file directly in the browser:. Just drag the file onto this browser window and drop it.

FSR file format:

To find out what program is needed to open FSR files, you need to determine the file format. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. If there are problems opening a file, you must first determine the file format used. Our examination of the FSR files comes to the following conclusion:

As a file extension, FSR isn't very common and predominantly uses a uniform format. However, the following two file formats are common:

• 80% of all FSR files have the same signature FS. These files are binary files, so they do not contain text, but only cryptic characters. The files are on average 3 MB in size and range from 370 KB to 19 MB. The file type is old but is used even today. Several words can almost always be found in the files, e.g. FSIB, BFIB, ODIB&, PLANE ALTITUDEft, PLANE LATITUDEdegrees, PLANE LONGITUDEdegrees, PLANE PITCH DEGREESdegrees, UserAircraft, EnviromentPDIB, <?xml version="1.0" encoding="UTF-8"?>, <SimBase.Document Type="ScenarioFile", <Descr>AceXML Document</Descr>, FLIB, FLTF, RECTMPFLT and <Filename>RECT. Such files are related to movie, landing, chap, lake, around, crosswind, first, video and take.
• 4% of all FSR files save the data in MP4 file format. MP4 is a multimedia container format used to store video and audio and allows streaming over the Internet. They consist of unreadable binary data. The files are 39 KB to 81 MB in size, with a median of 27 MB. Several words can almost always be found in the files, e.g. lmvhd.

The remaining 16% of all FSR files are files with no common format. Tagged as report. Just click the "Choose your .fsr file to analyze" button on this page to find out what your FSR file is.
