Opening Files with the Right Program
A brief introduction to understanding file associations in Windows.
Every file has a type, like .docx, .jpg, or .pdf. Windows uses file associations to open files with the correct program automatically. For example:
- .docx opens in Word
- .jpg opens in Photos
- .pdf opens in a PDF viewer
You can change the default app using Right-click → Open with → Always use this app. This ensures files always open in the program you prefer.
