About Folders
As with “100EOS5D” for example, the folder name starts with three digits (the 
folder number) followed by five alphanumeric characters. A folder can contain 
up to 9999 images (file number 0001 - 9999). When a folder becomes full, a 
new folder with the folder number increased by one is created automatically. 
Also, if manual reset (p.157) is executed, a new folder will be created 
automatically. Folders numbered from 100 to 999 can be created.
Creating Folders with a Personal Computer
With the card open on the screen, create a new folder named “DCIM”. Open 
the DCIM folder and create as many folders as necessary to save and 
organize your images. The folder name must follow the format “100ABC_D”. 
The first three digits are the folder number, from 100 to 999. The final five 
characters can be any combination of upper- and lower-case letters from A to 
Z, numerals, and the underscore “_”. The space cannot be used. Also note 
that two folder names cannot share the same three-digit folder number (for 
example, “100ABC_D” and “100W_XYZ”), even if the other five characters in 
each name are different.
