you have a typo in your code:
var fileExtension:String = myvar.substr(file.lastIndexOf(‘.’)+1, file.length-

should be:
var fileExtension:String = file.substr(file.lastIndexOf(‘.’)+1, file.length-

see the “myvar” -> “file”

thanks anyway, works perfect!

Or you can seek for the last dot, where anything beyond is the extension:

var myvar:String = “movie.flv”;
var fileExtension:String = myvar.substr(myvar.lastIndexOf(‘.’)+1, myvar.length-myvar.lastIndexOf(‘.’));
trace(fileExtension);

this works with all extension sizes :]
