File saveDialog() Class method File.saveDialog(prompt, select) Description The File.saveDialog class method presents the Save dialog box that is standard for the platform on which After Effects is running. This method overlaps somewhat with the easier-to-use filePutDialog() global function. Parameters prompt select select (Win) An optional prompt (expressed as a string) that is displayed as part of the dialog if the dialog permits the display of an additional message. This argument allows the pre-selection of the files that the dialog displays. Unfortunately, this argument is different on Mac OS and on Windows. Windows selection string is actually a list of file types with explanative text. This list is displayed in the bottom of the dialog as a drop-down list box so the user can select which types of files to display.The elements of this list are separated by commas. Each element starts with the descriptive text, followed by a colon and the file search masks for this text. Again, each search mask is separated by a semicolon. A Selection list that allowed the selection of all text files (*.TXT and *.DOC) or all files would look like this: Text Files:*.TXT;*.DOC,All files:* A single asterisk character is a placeholder for all files.
