File Management

During operation, the Analyzer generates various ASCII-format text output files
that are updated after each batch of concentration measurements is complete.
For example, one of the user output files is named CKBDS##-yyyymmdd-hhmm-
DataLog_User_Sync.dat where "CKBDS##" or similar is the instrument serial
number. The data files are created every 15 minutes.
The file name is generated from the instrument serial number, the date, and the
time when the instrument was started. For example:
CKBDS01-20070127-1029-DataLog_User.dat
CKBDS01 is the instrument serial number
20070127 is the date, 1/27/2007, in format yyyymmdd (to allow chronological
sorting of data files).
1029 is the time the file was started, 10:29 am, formatted as hhmm using a 24
hour clock.
The raw user data is contained in folders in the directory: C:\UserData
\DataLog_User\[year]\[month]\[day]\hour. This is data that has not been re-
sampled to exact 0.1s time intervals. There is a similar directory
C:\UserData\DataLog_Sync\... which includes data that is evenly spaced in
time at the data rate of the analyzer.
Data files are created every 15 minutes and stored for 90 days before they are
automatically deleted. The file deletion frequency and details can be modified in
the file: C:\Picarro\G2000\AppConfig\Config\Archiver\Archiver.ini. This is
explained below.
During data acquisition, the analyzer creates directories to store the data, based
on the date the data were acquired. After each datafile has been closed (every
15 mintes) it is moved to an archive directory, and a new file is started in the
original location. The archive directory is C:\Picarro\G2000\Log\Archive\ and has
subdirectories DataLog_Mailbox, DataLog_Private and DataLog_EventLogs with
files arranged by year\month\day\hour.
There are more complete datafiles which include additional information beyond
the concentration data including parameters such as instrument temperatures
