FileData: IIOStream;
The FileData property determines a thread linked with the opened/saved file.
When working with the FileOpenDialog component, the FileData property will contain the thread linked with the file that was selected after dialog box initialization and clicking the Open button.
When working with the component, one should set the thread in the FileData property, which is linked with the file, before dialog box initialization. After the dialog box is initialized and the Save button is clicked, the file will be saved using browser tools.
Size of the opened/saved file should not exceed 1 GB.
The property use is given in the example for IWebFileDialog.Execute.
