Canon EOS 20D Instruction Manual

61

The file number is like the frame number on film. There are two file 
numbering methods: [Continuous] and [Auto reset]. The images you 
take are automatically assigned a file number from 0001 to 9999 and 
saved in a folder (created automatically) that can hold up to 100 
images.

numbering], then press <

Turn the <

5> dial to select 

[Continuous] or [Auto reset], then 
press <

0>.

The file numbering continues in sequence 
even after you replace the CF card. This 
prevents images from having the same file 
number, so image management with a 
personal computer is easier.

Each time you replace the CF card, the file 
numbering will be reset to the first file 
number (XXX-0001). Since the file number 
starts from 0001 in each CF card, you can 
organize images according to CF card.

If folder No. 999 is created, [Folder number full] will appear on the LCD 
monitor. Then if file No. 9999 is created, “Err CF” will be displayed on the 
LCD panel and in the viewfinder. Replace the CF card with a new one.

For both JPEG and RAW images, the file name will start with “IMG_”. The file 
name extension will be “.JPG” for JPEG images and “.CR2” for RAW images.
