Memory Card Folder Structure
The images on a memory card are placed in subfolders of the [DCIM] folder labeled
[xxxCANON], where the “xxx” represents a number in the range 100 - 999.
•*Files with the THM extension are the thumbnail image files for the camera’s index replay
mode.
•The “xxxx” in file names represent four-digit numbers.
•**Each successive file shot in Stitch Assist mode is assigned a letter starting from “A,” which
is inserted as the third digit in the name. i.e. [STA_0001.JPG], [STB_0002.JPG],
[STC_0003.JPG]...
•All folders except the “xxxCANON” folders contain image settings files. Do not open or delete
them.
