• WhenMediaFIFOIsinUse
If not enough free space is available when saving a new data file to the SD memory card,
files are deleted in order from the oldest data update date/time to save the new file. This
operation is referred to as FIFO (First In First Out).
When saving the data files automatically, you can save the data so that the most recent data
files are constantly retained in the SD memory card. This method allow you to use the GX/
GP continuously without having to replace the SD memory card.

Media FIFO Save Operation
• The FIFO operation is carried out only when the following files are saved automatically. It
is not carried out when files are saved to the save destination directory through another
method.
Display data files, event data files, report data files, manual sample data files, and
snapshot data files
• Files that are deleted
All the files in the save destination directory are applicable to be deleted. However, the
following files are excluded.
Hidden files, read-only files, files in the subdirectory within the save destination directory
• The most recent 1000 files are retained. If the number of files in the save destination
directory exceeds 1000, the number of files is held at 1000 by deleting old files even if
there is enough free space.
• If there are more than 1000 files already in the save destination directory, one or more
files are always deleted before saving the new file. The number of files is not kept within
1000 in this case.
