The File Selection Window contains a three text fields along the top that allow you to change the location of where VisIt looks for files. The contents of directories and the selected files list are shown below those text fields. The left of the window lists the names of the directories that are subdirectories of the current directory. This list is commonly empty except for two entries that link to the current and parent directories. The list in the middle of the window contains the files that reside in the current directory and match the supplied file filter. The list on the far right contains the list of selected files. This window allows you to modify the contents of that list by adding and subtracting files from the list. When you are satisfied with the contents of the selected file list, clicking the Ok button will apply the Selected file list. Otherwise, clicking the Cancel button will undo any changes made to the Selected file list.
