4.1.5 Hard Disk File Names
The name of any file on the Fast data server built-in ATA card is
represented using the 8.3 file name format (8 characters in the file name
and 3 characters in the file name extension) originally adopted for
MS-DOS.
If a file to be subjected to an FTP transfer is specified only with a file
name that is not in the 8.3 format, it is converted to an 8.3-format file
name according to the following conversion rules.
Rules for conversion to 8.3-format file names
1 The first 8 characters in the specified file name are used as a
post-conversion file name.
2 The 3 characters in the specified file name between the first and
second periods are used as a post-conversion file name extension.
3 Any blank character in the specified file name is ignored.
Examples of converting to 8.3-format file names
1 “NCPROGRAM.DAT” → “NCPROGRA.DAT”
Because the file name has more than 8 characters, the first 8
characters are accepted as valid, and the post-conversion file
name becomes as stated above.
2 “NCFILE.TEXT” → “NCFILE.TEX”
Because the file name extension has more than 3 characters, the
first 3 characters in the file name extension are accepted as valid,
and the post-conversion file name becomes as stated above.
3 “NCFILE.PRG.TXT” → “NCFILE.PRG”
The characters between the first and second periods are accepted
as valid, and the post-conversion file name becomes as stated
above.
4 “NC PROGRAM.DATA.TXT” → “NCPROGRA.DAT”
Because the first 8 characters, excluding the blank character, in
the file name are accepted as valid, and the first 3 characters
between the first and second periods are accepted as an file name
extension, the post-conversion file name becomes as stated above.
NOTE
If the file names of different files on the host computer
built-in hard disk are converted to 8.3-format file
names for registration with the Fast data server
built-in ATA card automatically as described above,
the post-conversion file names may become
identical.
