Please try to collect your various postings into one -- USENET doesn't
lend itself to chat.

Compared to the code you posted, I would suggest:
 1. That you parse both the date and the hour in the filename (you
seemed to only parse the date);
 2. That you use the objects from the java.time package (e.g.
java.time.LocalDateTime) instead of the (essentially deprecated)
java.util.Date;
 3. That you put every file you find into a java.util.NavigableMap (e.g.
TreeMap) with the LocalDateTime you parsed as the key and the File as
the value;
 4. Then, when you have built that map with all the files in your
directory, you can search the map according to some input.

Sample code (not compiled) for item #4:

 NavigableMap<Temporal, File> indexedFiles;
 LocalDateTime reference = ...;

 //Files in the hour of 'reference'
 LocalDateTime hourStart =
reference.withMinute(0).withSecond(0).withNanos(0);
 LocalDateTime hourEnd = hourStart.plusHours(1);
 System.err.printf("Files in current hour (%s->%s):%n", hourStart, hourEnd);
 indexedFiles.subMap(hourStart, true, hourEnd, false).forEach( (time,
file) -> System.err.println(file.getAbsolutePath()) );

 //Files in the day of 'reference'
 LocalDateTime dayStart = reference.truncatedTo(ChronoUnit.DAYS);
 LocalDateTime dayEnd = dayStart.plusDays(1);
 System.err.printf("Files in current day (%s->%s):%n", dayStart, dayEnd);
 indexedFiles.subMap(dayStart, true, dayEnd, false).forEach( (time,
file) -> System.err.println(file.getAbsolutePath()) );

 //Files in the week of 'reference' is left as an exercise to the reader.
 //Cf. LocalDateTime#with(TemporalAdjuster) and
TemporalAdjusters#previousOrSame et al.
