....
try {
file=File.createTempFile("","");
String
path=file.getAbsolutePath().substring(0,file.getAbsolutePath().lastIndexOf("/"));
File oldFile=new File(path+"/"+fileName+".ext");
if (oldFile.exists()) {
oldFile.delete();
file=File.createTempFile("","");
}
file.renameTo(oldFile);
OutputStream os = Storage.getInstance
().createOutputStream(file.getAbsolutePath());
....
....
