Can I use fstream for working with files with the Nokia Qt SDK?

In my ap开发者_运维技巧plication (on Nokia S60 v3) I need to write and read some file from a device. Can I use the standard C++ fstream? Or do I need a Symbian API class?

Where can I read some information about this?

You can use fstreams with Open C++ STLport library but since you're working on Qt, I'd suggest you use QFile instead.
