time and date of the last file write operation. On the bottom of the listing will be the number of
bytes used and the number of bytes free. Below is a sample listing.

Adding up the bytes used and the bytes free ends up with 3,948,111. This indicates the internal
memory on this unit is using a 4 megabyte data card. A 4 megabyte data card would take over
three years to fill up logging 4 data values every 15 minutes. A 4 megabyte card was the smallest
card shipped in the XL series data logger and as of 2008 most units are shipped with a 16
megabyte card or bigger depending on availability. The smaller cards are harder to find so the
trend is always towards the larger sizes.
The listed time and date for a file shows when it was last modified.
The XL Series data logger will use or create a few different file types. This are listed below.
Data Files
Data files on the internal data card will have a number extension of .000 to .099. As data files are
copied to the external data card the extension will change to a letter followed by the old
extension number such as .A00, .A01, etc. If the file already exists on the external data card the
letter will be increased by one character value.
Configuration Files
Configuration files will have a .CFG file extension. The file name will be the same as the site ID
of the unit the file was created with. Configuration files may also be edited and renamed on a PC
and then copied back to a data card.
.NEW File
The .NEW file is created if the “Log .NEW File” option is set to Yes. The .NEW file will contain
the same data that is in the main data file, but this file can be automatically transmitted and
erased by using the DUMPNEWDATA and ERASENEWDATA commands in the command
