By default, all software supports multiple file extensions. Qt SDK supports at least 8 different file extensions. The basic files that Qt SDK supports are .PRO. However, not all of the extensions listed on the list are always used to save the effects of work in Qt SDK. Very often, files with such extensions are used as source data files used by Qt SDK.
Qt SDK can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via Qt SDK and try to save it in another file format, also supported by Qt SDK.
