Excuse me, I have another question about this.
The app has to check if the file is already present. It could happen when
the user types the same file name before the temp directory has been
emptied.
So I have to check it and delete before creating it again.
But I wonder if temp files are special files, how to check it without any
uncertainty?
Thanks
