Question

I want to add a comment to a file(video,txt,etc...). right click on a file on windows the comment should appear.

File tempf= new File (Environment.getExternalStorageDirectory().getAbsolutePath()+"/picedittemp");
tempf.setcommentOrTittle("mycomment to file");                                              

Answer 1

Not all files contain a comment field so there is no standard way of doing it. Each file type however will have a library which will allow you to modify its tags. An mp3 for example has the JAudioTagger library which allows you to set tags like this.

//No guarantee this will work (just an example)

 File track = new File("C:/path/to/song.mp3");

 AudioFile f = AudioFileIO.read(track);

 f.getTag().setField(FieldKey.COMMENT,"My Comment");
