4.4 File
Sort
Full pathnames ("/DCIM/100CANON") are sorted in alphabetical order.
If there are six directories;
"/";"/CUSTOM";"/FREE";"/DCIM/100CANON";"/DCIM/101CANON";"/DC97/CTG_0020", they are
sorted in the following order:
"/" -> "/CUSTOM" -> "/DC97/CTG_0020" -> "/DCIM/100CANON" -> "/DCIM/101CANON" ->
"/FREE"
<File name sorting specifications>
Files specified in the DCF (Design rule for Camera File system) standards (“the file name with 8 characters
excluding the extensions, and with the latter 4-digit figures”) are sorted to the top of the list by priority.
Also, DCF files are sorted using the last 4-digits, which are recognized as a number, and sorted in
ascending order. For non- DCF files, if the file name includes numbers, they are recognized as numbers,
and are sorted in ascending order also.
Sorting is preformed for each directory.
As the i900D/i905D can work with up to 999 files, the 1,000
th
file and later are not sorted.
Detailed sorting specifications are as follows:
File order is determined using the rules in the following order to sort from Low to High in ascending order:
A. When one is a DCF file, and the other is a non-DCF file, the DCF file is low.
eg. IMG_0001.JPG < IMG_FILE.JPG
B. When both files are DCF files,
B-1. The last 4-digits (numbers) of each file name are recognized as a number, with the smaller number
Low.
eg. IMG_0001.JPG < IMG_0002.JPG
IMG_0005.JPG < 07240010.JPG (The latter figures are 0005 and 0010.)
B-2. When the result of the comparison in B-1 above is the same, the files are then sorted in alphabetical
order.
eg.
ABC_0001.JPG
<
ABD_0001.JPG
IMG_0001.JPG < IMG_0001.TIF (J is “lower” T.)
C. When both files are non-DCF files,
C-1. From the beginning of the file name, the position of first number is deleted, sorting by distance in
ascending order..
eg. IMG001.JPG < IMG_001.JPG
C-2. When the result of the comparison in C-1 above is the same, numbers are sorted in ascending order.
eg. IMG001.JPG < ABC002.JPG
C-3. When the result of the comparison in C-2 above is the same, the length of the numerical string is
sorted in ascending order.
eg. IMG001.JPG < ABC0001.JPG (The length of the former is 3, and the latter is 4.)
C-4. When the result of the comparison in C-3 above is the same, the next character is recognized as the
top of the file name, and the process returns to C-1.
eg. A_1_3_.JPG < A_1_3_1.JPG (as the results of the comparison in the first (1) and
second (3) loops are the same, in the third loop, the distance to the next number is 0.)
C-5. When the result of repetition from C1 to C4 is the same, the files are sorted in alphabetical order, as
in B-2.
eg.
A_1_2.JPG
<
A_1_2.TIF
4.5 Date
It is possible to print the date in the following three patterns, or to not print the date.
MM/DD/YYYY
DD/MM/YYYY
YYYY/MM/DD
However, in DPOF mode, the DPOF setting is used.
For the date layout and size, refer to the print layout.
The date data to be used in date print are as follows:
Print Mode
Exif file or non-Exif file
Date data to be printed
DPOF mode
-
Date in the DPOF file
Exif file: Creation date of the image data exists.
Date when the Exif file was created
Non-DPOF mode
Non-Exif file
Updated date of the file system
2 - 11
