The name is based on the date thefile was created and the type of data it contains. The format for the name isYYYYMMDDnz.dat, where:• YYYY are the four digits of the year.• MM is the month.• DD is the day.• n is the sequence letter (‘A’, ‘B’, ‘C’, and so on). This letter indicates the sequence inwhich the files were created. You can have up to 26 files (‘A’ to ‘Z’) per day. Atmidnight, the sequence starts at ‘a’ again.• z is the file type: ‘L’ (uppercase L) is for alarm.If you are using short file names, or if the path where the log files are stored does notsupport long file names, the format for the name is YYMMDDnz.dat, where YY are thelast two digits of the year.Example: Log file nameThe log file named 20051015BL.dat was created in the year 2005, month 10, and day 15.The ‘B’ indicates that this is the second file created that day.
