The File Table: A file table is generated each time a live or a batch module create
syllable tables or raw features tables. The file index then appear in those feature tables as
an index to the file table, which tells you more about the identity, location and attributes
of each of the sound files. As mentioned earlier, the File Table is an important utility that
allows you to query arbitrary subsets of your raw data from any set of processed data.
Here is the File Table structure:
Note that the file_age and the bird_age can be used to design queries for retrieving
subsets of data. However, the file age is a bit less accurate than the ms table serial
number time stamp. That is, the number of days elapsed from 1900 is accurate but the
fraction of the day is not the same as number of milliseconds elapsed from midnight but
the DOS time prompt, with accuracy of about 2 seconds. - more on this in the xxxx.
