while ((byteRead = (byte) fis.read()) != -1) {
fos.write(byteRead);
}

System.out.println("about to delete ");
boolean deletionSucessful= false;

They don't really document the reasons why a delete might fail, but the main one I've found is - if anyone else is currently accessing the file. In this case, the most likely cause is your fis object, which is still open and ready to read from the file (even though it's at the end of the file). Add an fis.close() right after you're done copying. In general it's a good idea to always close any stream immediately after you're done with it - otherwise you don't know when it will be closed. (Garbage collection will probably take care of it eventually, but you don't know when.)
