Read the end of a file name
Look at a file name and know what sort of thing it is.
The letters after the last dot say what sort of file it is: .pdf a document, .jpg a photograph, .docx something written.
It is the label on the tin. The computer reads it to pick which program opens the file.
Key points
- The letters after the last dot name the sort of file
- The ending decides which program opens it
What to remember
- The ending says what will open, before you press.
- The ending says what sort of thing. It never says who sent it.
