Copy specific files from a directory and subdirectories into a target folder in mac

Question

I have a directory structure in which i have some specific files (say mp3 files) organised directly or in subdirectories(upto n levels). For example:

• Music Folder
  • a.mp3
  • folder2
  • folder3
  • b.mp3
  • c.mp3
  • folder4
  • d.mp3
  • folder5
  • folder6
    • folder7
    • folder8
      • e.mp3

Now, what i require is to copy all files (.mp3 file) from all the folders and subfolders into another target folder. So my target folder would be like this:

• targetFolder
  • a.mp3
  • b.mp3
  • c.mp3
  • d.mp3
  • e.mp3

I tried the answers from following questions: Recursive copy of specific files in Unix/Linux?

and Copy all files with a certain extension from all subdirectories, but got copied the same directory(and subdirectories) structure.

Any help or suggestions?

Answer 1

cd "Music Folder"
find . -name "*.mp3" -exec cp {} /path/to/targetFolder \;

Answer 2

Using java code, i achieved this as follows:

Path start = Paths.get("/Users/karan.verma/Music/iTunes/iTunes Media/Music");
        int maxDepth = 15;
        try(Stream<Path> stream = Files.find(start, 
                    maxDepth, 
                    (path, attr) -> String.valueOf(path).endsWith(".mp3"))){

            List<Path> fileName = stream
                    .sorted()
                    .filter(path -> String.valueOf(path).endsWith(".mp3"))
                    .collect(Collectors.toList());

            for(Path p : fileName) {
                Path path = Paths.get("/Users/karan.verma/Desktop/TestCopy/"+p.getFileName());
                Files.copy(p, path,StandardCopyOption.REPLACE_EXISTING);
            }
        }catch(Exception e){
            e.printStackTrace();
        }
