COMPACT FLASH FILE STRUCTURE
In the root directory of the Compact Flash card, the DVR will create a
new subdirectory for each day of recording. The subdirectory is named
as follows:
Mmm.dd.yyyy
Mmm = 3 letter month abbreviation, e.g. Jan, Feb, Mar, ...
Dec
dd = day (01 - 31)
yyyy = 4 digit year, e.g. 2006
Each subdirectory will contain one or more AVI files named as follows:
ssssssssssssss_Mmm.dd.yyyy_hh.mm.ss.avi
sss.. = User defined system name. This name can be from 0
to 14 characters in length. This field is free-form for
the end user to define car number, officer name,
whatever within the 14 character limitation. The user
is free to put spaces within this name, but these are
replaced with underscores ('_') in the filename.
Mmm.dd.yyyy = same as directory name
hh.mm.ss = 24 hour time in hours, minutes, and seconds
.avi = AVI file extension
NOTES:
. If the system name is 14 characters in length, then there
is no trailing underscore after the system name.
. File names can contain a 'suffix' which indicates that the
file is a continuation of a recording (every 10 minutes, the
DVR starts a new file). Also, an event can be marked with
a suffix. The suffixes are:
'+' : this is a continuation file
'#' : this file contains an 'event' of interest
The suffix is placed just prior to the file extension, e.g:
Jan.01.2006_01.00.00.avi /* First file */
Jan.01.2006_01.10.00+.avi /* Continuation file */
Jan.01.2006_01.12.15*.avi /* Event file */
