Viewing a file

I am saving a file to a folder and i want to view the file through program without going to that directory and opening that file.How can i do that?

You use QFile to open and read the file.
Then something like a QTextEdit to view the file (if it is a readable text file).
Other viewers are available to view graphics files.
