Section 8. Working with Data Files on the PC
given a numeric suffix prior to the *.dat extension. The first file is stored with a
_1 at the end of the root file name (e.g., TOA5_Mytable_1.dat). The number is
incremented by one with each new file saved. If a file with the same name is
found, the number will be incremented to the next available number.
Use Removemarks – When a compact flash card is removed from a CR1000
or CR3000 datalogger, a special mark is inserted in the last record. The
Removemark is similar in nature to the Filemark. In CardConvert, you can split
a file into multiple files, separated at the Removemarks, by converting the file
with the
Use Removemarks option selected. As with the Use Filemarks
option, the first file stored uses a _1 at the end of the root file name and the
number is incremented by one with each new file saved.
Use Filemarks and Use Removemarks can be selected at the same time, to
create a new file from the data table any time either of the marks is
encountered.
Use Time – This option is used to store the converted data into files based on
the timestamp of the data. When the Use Time check box is selected, the Time
Settings button becomes available. This button opens a dialog box that is used
to set a Start Date and Time , along with an Interval , which are used to
determine the time frame for the data that goes into each file. Note that the
Start Date and Time are not used to specify the actual time and date to begin
processing the file; rather, they are used as a reference for the file interval.
Processing always starts at the beginning of the file.
When Use Filemarks, Use Removemarks, or Use Time is selected, the
Create New Filenames option is disabled. New file names will always be
created.
Convert Only New Data – When this option is selected, only data that has
been collected since CardConvert’s last conversion of the specified file(s) will
be converted. The first time CardConvert is used on a file, all data will be
converted. On subsequent conversions, only new data will be converted.
However, if CardConvert cannot tell what data is new (i.e. if data on the card
has wrapped since the last conversion), all data will be converted. This option
can be used with
Append to Last File to create a continuous file with no
repetition of data.
8.3.2.3 File Naming
Time/Date Filenames – When this option is selected, the date and time of the
last record of data in the file will be appended to the end of the base file name.
The suffix includes a four digit year, a two digit month, a two digit day of
month, and a four digit hour/minute. When this option is selected,
Use Day of
Year becomes available. If this option is selected, the Julian day (day of year)
will be used for the suffix instead of the year/month/day/hour/minute suffix.
Create New Filenames – When the Create New Filenames option is selected,
CardConvert will add a _01 to the filename, if a file of the same name is found
(e.g., TOA5_Mydata_01.dat). If a *_01.dat file is found, the file will be named
with a _02 suffix. If the
Create New Filenames check box is cleared and a file
with the same name is found, you will be offered the option to Overwrite the
existing file or Cancel the conversion.
