 During the operation, the P30U transducer creates folders
and files on the SD/SDHC memory card or in the internal file system
memory. An example folder structure is shown on fig. 27.
Fig.27. Folder structure on the memory card (internal file system)
 Apart from the ARCH folder where recorded data are stored,
also the SYSTEM folder is created on the memory in which the
start.txt
file is stored to save the date and hour of installation of the memory card
(also when starting the device after the power supply has been lost).
 Data on the memory card or internal file system memory
are stored as files located in folders corresponding to the device name
and serial number – see fig. 27. File names correspond to the date
of recording and have the following format
XXXX_YY.Dzz, where
