Due to its nature of name of a file, entryYYMMDD-HHMMSS.txt must be univocal, and therefore it can be considered as the ID field of a DB table.

Comment DBs are associated to the entries using the file name (ID) of the entry, deprived of its extension (.txt) as the name of the directory which will contain them.
