FCGI	File extension: FCGI
	File type:	executable script file

What is an FCGI file?

FCGI files mostly belong to FastCGI Daemon.

FCGI files are used in FastCGI environments to handle web server tasks. They work as executable scripts or programs that process web requests outside of the main server process, which helps to reduce overhead and improve response time.
Key points compiled by FilExt.com:

The files can be in ELF format as compiled executables (often run as a FastCGI daemon, such as with php-cgi).

Some FCGI files are in JFIF format, serving as image files for systems like IIPImage, which uses a web server gateway interface. More details can be found on the IIPImage website.

Other variants are simple FastCGI script files, where the code is read and executed by the FastCGI manager. Additional information is available at the FastCGI Archives.

In some cases, they are used as proxy auto-config files for web server scripts.

How to Open and View:
FilExt.com tip: If the file holds script text, you can open it in a text editor to check its source code. If it is a binary executable, it is intended to run within a configured FastCGI environment and should not be opened directly.

How to open FCGI files

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