Drop the files into different directories based on the filename

Question

Hi,
I had a reqiuirement based on the file name, i should drop the files in to different directories.
I can get the filename through variable substitution in receiver file communication channel, now i want to drop the file into different folders based on conditions.
suppose, if the file name is DDDX234
i should do substring of filename0+(4), if the value is L then i should drop in X directory
suppose, if the file name is DDDY234
i should do substring of filename0+(4), if the value is L then i should drop in Y directory.
How can i drop the file into differnent directories based on filename.
Thanks

Thanks Michal,
I mapped the directory and filename to the target header in the mapping
Filename --> UDF --> Header(target)
and in the receiver channel checked the ASMA and given * in the filename and directory name.
But in runtime iam getting the error as
Attempt to process file failed with com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header
MY UDF is
public String Directory(String a,Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key  = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "Directory");
String FileName = conf.get(key);
FileName = a;
conf.put(key, FileName);
%%%based on filename the directory should change
String Directory = conf.get(key1);
Directory = "/SAPInterface/XI/PPD/DHX/out";
conf.put(key1, Directory);
return "";
Help me in correcting this error.
Thanks
