⚠ Be careful with .c files.

It's important to know that the .c file extension can be used by various programs, not just the ones you expect. This includes potentially harmful software or malware that might create .c files. Be cautious when dealing with .c files from unknown sources.

🔴 Can't open a .c file?

When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:

If you don't know how to change the default app for the .c file, check the FAQ.

🔴 Can I change the extension of files?

Changing the filename extension of a file is not a good idea. The extension of a file serves as a hint to the operating system and various software programs about the type of data contained within the file. When you alter a file's extension, you essentially modify how software applications interpret and handle that file. Every file has a specific format, also known as its file type or file format. The problem is, changing the file extension does not change the file format.
