Opening an FFT File
The FFT file type is primarily associated with LTspice.
What is an FFT file
FFT files mostly belong to LTspice. FFT files are simulation data files used by LTspice. They hold the results of a Fast Fourier Transform analysis run on circuit signals.
This file records how a time-domain signal is transformed into its frequency components, showing both amplitude and phase.
Key points compiled by FilExt.com include:Purpose: Stores FFT results from circuit simulations. Usage: Viewed with LTspice to analyze frequency responses. Content: Contains numerical data representing the frequency-domain characteristics of a circuit. FilExt.com note: For additional details, check the LTspice simulator page.

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

Programs that open and convert FFT files:
- LTspice
See the previous paragraphs to learn more about the main application. FFT files are often referred to as LTspice data files because this type of file is primarily created or used by this software.

an fft simulation result file is a special file format and should only be edited and saved with the appropriate software.
How to solve problems with FFT files
- Associate the FFT file extension with the correct application.
- Update your software that should actually open simulation result files. Because only the current version supports the latest FFT file format. Search, therefore, e.g. on the manufacturer website after an available LTspice update.
- To make sure that your FFT file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
