So i have to search for ".mp3" files in all folders and

display into table. Can anyone tell me that how can i search,
retrieve .mp3
file and play this particular file into my apps.
Briefly, scan the disk using NSFileManager. You can use -
enumeratorAtPath: to get an NSDirectoryEnumerator that will perform
the scan. Gather the results into some sort of data storage that suits
the purpose - a simple array would probably do, such as NSMutableArray.
To display the results in a table, NSTableView hooked to a controller
e.g. NSArrayController that uses the above array as its data model.
To play an mp3 file, the simplest way is to use Quicktime via QTKit.
e.g. [QTMovie movieWithURL:error:] followed by [myMovie play];
