// Code folding example
// Click the fold icon to hide code blocks
+ int main() {
|    std::cout << "Hello, world!" << std::endl;
|
|    // More code
| }

// Indentation example
// Auto-indent code to improve readability
if (condition) {
     // Code block 1
} else {
     // Code block 2
}

### 2.2 Optimized File Management
