All about CIRC Files

The CIRC file type is primarily associated with Logisim-evolution.

CIRC	File extension: CIRC
	File type:	circuit design file

What is a CIRC file?

CIRC files mostly belong to Logisim-evolution. CIRC files store circuit design and simulation data. They are used by specialized applications to describe circuit layouts.
This file type often uses an XML structure, especially in designs made with Logisim-evolution. With this structure, the file holds details such as component settings, wiring configurations, and simulation parameters. Some CIRC files, like those from Festo FluidSIM, use a GZIP compression method to store similar circuit information.

File structure: The XML format makes it possible to view or edit the file in a text editor if needed.

Software support: Open this file with Logisim-evolution for digital circuit design, or with Festo FluidSIM for fluid circuit projects.

Editing practices: It is best to use the designated simulation software to avoid errors.

FilExt.com tip: For further details on Logisim-evolution, see the Logisim-evolution webpage.

How to open CIRC files

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

Programs that open and convert CIRC files:

Logisim-evolution
See the previous paragraphs to learn more about the main application. CIRC files are often referred to as Logisim-evolution cads because this type of file is primarily created or used by this software.
Logisim, Festo FluidSIM
A .CIRC file most commonly refers to a Logisim circuit design file. Logisim is an educational tool for designing and simulating digital logic circuits. These files, predominantly in XML format, store the circuit's components, connections, and other design elements. Less frequently, .CIRC might point to a compressed file format associated with Festo FluidSIM, a software used for designing and simulating pneumatic and hydraulic circuits. This file format is classified as Circuit Design or Simulation File.

a circ circuit design file is a special file format and should only be edited and saved with the appropriate software.

How to solve problems with CIRC files

Associate the CIRC file extension with the correct application.
Update your software that should actually open circuit design files. Because only the current version supports the latest CIRC file format. Search, therefore, e.g. on the manufacturer website after an available Logisim-evolution update.
To make sure that your CIRC file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
