When synchronizing data files that exceed the 5 million point range, the file is used
as the start file and succeeding files are joined. If 5 million points is not exceeded
when the last file is joined, files before the start file is searched in order, and files that
would not cause 5 million points to be exceeded are joined. In this case, because
the files before the start file are also joined to the previous synchronized file, two
synchronized files for this file would exist. If you open a file before the start file and
perform synchronization, the viewer displays the first file the OS finds (either of the
two existing synchronized files). In such cases, it is recommended that the files you
wish to join are selected so that the limit is not exceeded, copied to the user’s working
folder, and synchronized there.
• Divided files can be joined up to the point in which the size of the joined file reaches 2
GB.
CF Fle Jonng Functon
Data saved to the CF card on the MX100 can be joined.
• The data that can be joined are CF files that were created on the same unit from
record start to record stop.

• Data are joined by file groups of data with multiple measurement intervals of the same
file number.
• If a number of files equalling the number of measurement intervals of the specified file
number (if three measurement intervals are specified, the number would be 3) does
not exist in the file group, files just prior to the file group of the relevant file number are
joined.
• The resulting files that are created are limited to five million points/2 GB.
• The extension of the joined files is .mxc.
The operation is carried out by choosing File > Join in the menu. Also, when opening
data files, if you choose data saved to the CF card in the MX100 main unit, the “Join
related files” dialog box appears and the files are joined.
CF files or joined data files displayed in the active window can themselves be joined, and
Join in the menu is enabled.
If the data files displayed in the active window are not CF or joined files, Join is disabled
in the menu.
Note
When joining or performing other such processes, copy the data files onto the hard disk of the
PC from the CF card first.
