Windrunner and QTP can be used for both UI and functional testing and file testing.

@ Shweta_Singhai (Lady in question :))

All these tools are proprietary tools; meaning companies need to pay for the license.
Windrunner, QTP and Silk test are all used to test GUI, functionality and files. Windrunner is becoming obsolete as it is being replaced by QTP. While Silktest is similar to QTP, it's license costs less than that of QTP.
Yes, QTP uses only VB script while Silktest used its own proprietary language - 4Test.Windrunner uses C language.

Loadrunner as the name suggests is used for performance/load testing.
