yes it only searches for .wav files.

but my problem is this.. for example:

1.the items in listbox1 are superman, batman and flash.
2.now i only have superman.wav in my folder.
3.when i click the search button, listbox2 displays superman.wav but it also displays batman.wav and flash.wav
4.batman and flash should be displayed on listbox3 because i do not have batman.wav and flash.wav.

can you help me solve this? im really stuck with this. sorry for giving u a hardtime. thanks dude.
