FileOpen()
and
FileWrite()
can be used to create HTML pages, but
this requires first writing the file to the datalogger’s USR, CRD, or
USB drive. It is less convenient, and the page will be only as
current as it is written to the file.

FTP Server
With an NL121 attached, the datalogger will automatically run an FTP server.
This allows Windows Explorer to access the datalogger file system via FTP. In
the FTP world, the “drives” on the datalogger are mapped into directories (or
folders). The “root directory” on the datalogger will include CPU and possibly
USR and/or USB. The files will be contained in one of these directories. Files
can be pasted and copied to/from the datalogger “drives” as if they were drives on
the PC. Files on the datalogger drives can also be deleted through FTP.
