2) File name, extension
• The corresponding file for the file transfer is designated.
• The file name must be designated according to the GX Developer file name
rules.
Alphabets (uppercase), numbers, symbols, can be used. Alphabets
(lowercase) cannot be used.
File name : Max. 8 characters
Extension: Max. 3 characters
• For the extension (identifier), the name fixed by the QCPU must be used.
The corresponding file extension is designated as seen in section 5.6.2.
• See the GX Developer Operating Manual for the details about the file names
and extensions.
• When using a FTP operation command which can designate multiple files, the
files (file names and extensions) are designated using wild card symbols,
" / ?."
: Files containing the characters before " " and any set of characters
(including none) replacing the " " are designated.
(Example. 1) When designating all files with the "QPG" extension
.QPG
(Example. 2) When designating file names which start with "MAIN" and the
extension is "QPG"
MAIN .QPG
? : The files containing the text string designated (including none), replacing ?
with any character including none. ("?" can be used multiple times.)
(Example. 1) The letter after "MAIN" is any character and the extension is
"QPG"
MAIN?SEQ.QPG
(Example. 2) To designate all files whose extension start with "QP"
.QP?
(Example. 3) To designate all files whose extension start with "Q"
.Q??
POINT
(1) In the description of the FTP operation commands, the file name indicates both
the file name and extension.
(2) It is recommended to use the following method to treat the file name from the
external device.
• Use the ASCII code characters (upper case for the alphabet letters) for the
file to be written to the FTP server.
• Do not change the file name for the file read from the QCPU.
(3) Each memory for QCPU does not have any sub-directories.
Each file is stored in the root directory.
