> # As IllegalArgumentException is not caught, the file name is not printed,
> which is not friendly for letting users find which file is broken.
> # After I modify the codes, I find the "broken" file is a zero byte file.
> e.g.:
> !image-2020-02-10-19-54-46-410.png!
>
> So, try to catch all exceptions to print the broken file name firstly, and
> skip and report incorrect files when checking these files (And I think this
> kind of files, i.e., 0-byte files, can be deleted)
