Selecting the Media, Folder, and Recording Method About Folders As with "100EOS1D" for example, the folder name starts with three digits (folder number) followed by five 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.80) 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 memory 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 spaces 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. 76
