Library of functions in Macromedia Director 11 needed

Hello, I need a set of Lingo functions for a Macromedia Director project. 1) a function to shrink (no enlarge) and resize an image cast member and/or image before being displayed on stage to fit a rectangle on stage preserving the aspect ratio. 2) if technically possible, load asinchronously the FILES of an entire folder consisting in images, videos and text files (txt or rtf) into a cast. Clean previously the cast A Cancel function should allow stopping the operation. The folder is from the local harddisks, CDs, not Internet. Asynchronous means the projector is not blocked at all during load, so the user can issue another command. If issuing the same command for another folder, a previous incompleted load should be first stopped. 2b) same as function 2), but instead of loading the entire folder, loading just a list of files passed through a list. 2c) loading a list AND the contents of the entire folder. The list to add can contain files from other paths 2d) loading like 2), 2b) and 2c), but being able to exclude certain files, being also passed as a list 2 continued) on output, after successful loading, the function returns a list of files loaded (according to the rules above), each entry having 4 components: - cast member number where it was loaded - path - filename - extension Sample call: loadFiles(castNameToFill, folderName, listToAdd, addMode, listToExclude) addMode can be: append to the folder's content OR add only the files from the list 3) loading ONLY the folders from a certain folder based on the same criteria as above: loadFolders(castNameToFill, folderName, listToAdd, addMode, listToExclude) returns: - path (without the last folder) - folder Thank you, Constantin
