Automatic File Naming (Auto Naming)
Numbering (Numbering)
The WT1800 automatically adds a four-digit number from 0000 to 0999 after the common name specified using
the File Name setting and saves files.

The date and time when the file is saved are used as its name. The file name specified for the File Name setting
is ignored.

Sequence number (0 to 9 then A to Z) for when multiple files
are saved at the same time (second)
A sequence number is appended to the date and time when multiple files are saved at the same time (second).
The number starts at 0 and is incremented by one each time a file is added. The number 9 is followed by letters
of the alphabet.
OFF
Disables the auto naming feature. The name that you specify using the File Name setting is used. If there is a
file with the same name in the save destination folder, you cannot save the data.
Save Destination Folder for Storage Caused by User-Defined Events
In the drive specified in the Store Set menu, a folder is automatically created with the date (year, month, and
day) as its name, and data is saved to files in that folder whose names are specified by the auto naming feature.
If the number of files in the save destination folder exceeds 1000, a new folder is automatically created with the
date and an incremented sequence number (000 to 999) as its name, and the data continues to be saved in the
new folder.
File Name (File Name)
You can set the common file name that is used when the auto naming feature is turned off or when the auto
naming feature is set to Numbering. The maximum number of characters that you can use for file names and
folder names is 32 characters. The following restrictions apply.
• The following types of characters can be used: 0 to 9, A to Z, a to z, _, –, =, (, ), {, }, [, ], #, $, %, &, ~, !, `,and @.
@ cannot be entered consecutively.
• The following character strings cannot be used due to MS-DOS limitations.
AUX, CON, PRN, NUL, CLOCK, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, COM1, COM2,
COM3, COM4, COM5, COM6, COM7, COM8, and COM9
• Make sure that the full file path (absolute path from the root directory) is less than or equal to 255 characters
in length. If it exceeds 255 characters, an error occurs when you perform a file operation (such as save, copy,
rename, or create folder). When an operation is being performed on a folder, the full path is up to the name of
the folder. When an operation is being performed on a file, the full path is up to the name of the file.
The following additional restrictions apply when you use the file name auto naming feature.
• If you set auto naming to Numbering, a file name will consist of the characters that you entered for the file
name and a four-character sequence number.
• If you set auto naming to Date (date and time), the characters that you entered for the file name will not be
used. File names will only consist of the date information.
