Opening downloaded files

Opening files

1. Go to your Downloads folder
2. Double-click the file
3. Your computer opens it with the appropriate program

If “Open With” appears

Sometimes Windows or Mac asks which program to use. This happens when:

• Multiple programs can open that file type

You can check “Always use this app” to set a default.
