I have an array that looks like this:  
100\_0061.JPG,100\_0064.JPG,100\_0068.JPG,100\_0069.JP G,test.swf,test.fla, test.psd

and the code that is building it:  
//jpgs to load  
basePath = mdm.Application.path + “presFiles/”  
var myFiles:Array = mdm.FileSystem.getFileList(basePath, “_._”);  
numberOfFiles = myFiles.length

How can I remove fla and psd files and update the length of the array. Or, how can I filter the array to only show swf and jpg files?
