Description
The ExpandedFileNames governs whether the value of the FileName property is expanded to a fully qualified path name based on the currently selected directory.
By default ExpandedFileNames is true and FileNames are expanded as they are entered. Otherwise, the FileName property is not expanded and the QDB file opening and closing routines will look for the specified file in the current directory. Such behavior affords a greater flexibility but can be problematic: e.g., if the current directory is changed unexpectedly QDB may not be able to find the required file and then go ahead and create an empty one in the current directory leaving yuor application to comaplin about empty data files.
