What is MIME type "application/x-logisim-circuit"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-logisim-circuit is a MIME type used for files that store digital circuit designs created in Logisim. It tells software that the file contains a circuit layout meant for simulation and digital logic analysis.

These files are usually stored as XML-based text. They hold details like components, wiring, and settings that define a circuit’s structure.

• Main Use Case: Designing and simulating digital logic circuits in Logisim.
• Educational Use: Helpful for students and educators to model and study complex circuitry.
• Practical Use: Used by hobbyists and professionals to prototype and test circuit ideas before actual implementation.

Files with this MIME type typically have the CIRC extension. This custom designation (noted by the x- prefix) means it is not an official standard but is widely recognized within its application domain.
