How File Upload works
File Upload works best when you understand the input, choose the right concept, run a small example, inspect the output, then reuse the pattern in a real task.
Where File Upload is used
- File Upload is used when teams need to solve one practical task.
- It commonly appears in a small real project feature, using sample input, output and edge cases.
- It is useful in debugging because the input, rule and output are visible in a small example.
