■ About File Names
When Recording to Memory or to Media
A maximum of 5 alphanumeric characters are available for use in designations. (Prohibited
characters ．，；：<>[]*?="/\|) The system attaches a 3-digit ID number (starting from 001) to these 5
characters to make a total of 8 characters. If the designated character is 4 or less, the portion between the
characters and the 3 digits will be filled with “0”, and the number of characters in the file name will become 8
in total.
When Recording to a PC
When recording to a PC, or when recording to a PC while recording to memory or media, there is no
restriction on the length of the file name. (Prohibited characters ．，；：<>[]*?="/\|) In the entry box on the
right of the file name, you can choose how many digits to use for the ID numbers appended to the file name.
Use up to 8 digits for the ID number. For example, if you enter 2 in the entry box, the number of recordable
files is up to 99.
Data files have the extension “.dat”. Header files have the extension “.hdr”.
Do not add numeric characters to the end of a file name. If you do, the following problem may occur.
Example: Suppose you specify the file name as "LX10", the 8-character file names are constructed as
follows:
LX100001
↓Increment
LX100002
↓Increment
LX100003
If you then specify a new file as "LX1" and record it to the same folder, the system will find that there is an
existing file called LX100001 and so, to prevent overwriting this file, the system will use LX100004 as the
new file name.
