Where does NXPowerLite save my files?

NXPowerLite > Support Help
By default, NXPowerLite will save an optimized file in the same folder as the original and add '(NXPowerLite)' to the optimized file's name. You can change this behavior by selecting 'Settings' from NXPowerLite's 'Tools' menu and clicking on the 'Optimized Files' tab.
