About Folders
As with “100EOS1D” for example, the folder name starts with three digits 
(folder number) followed by five alphanumeric characters. A folder can contain 
up to 9999 images (file No. 0001 - 9999). When a folder becomes full, a new 
folder with a higher one-up folder number is created automatically. Also, if 
manual reset (p.89) 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 “100ABC_D” format 
where the first three digits is 100 - 999 followed by five alphanumeric 
characters. The five characters can be a combination of upper- or lower-case 
letters from A to Z, numerals, and an underscore “_”. There can be no space in 
the folder name. Also, folder names cannot have the same three-digit number 
such as “100ABC_D” and “100W_XYZ” even if the letters are different.
