> Components: storage

> *Introduction*
> When consecutively inserting data into an existing directory, each files must
> have different names. To avoid the duplicated name problem, a unique sequence
> number is appended to the end of the file name. In addition, the max sequence
> number of pre-existing files is first found before starting writing to the
> final output directory.
> *Problem*
> When finding the max sequence number of pre-existing files, those files are
> not sorted by their sequence numbers. This finally causes the duplicated file
> name problem.
