Auto Reset; Manual Reset - Canon EOS 30D Instruction Manual

Auto Reset

When the CF card is replaced with a newly-formatted CF card, the
folder numbering and file numbering will restart from the beginning
(100-0001). It will start from folder number 100 and file number 0001.
This is convenient when you want to organize images according to CF
cards. If the replacement CF card contains images recorded previously,
the file numbering will follow the highest file number (in the highest
numbered folder) in that CF card.

Manual Reset

This creates a new folder automatically numbered with the next higher
number, and the file number restarts from 0001. Images captured
thereafter are saved in this new folder.
The file numbering method (Auto reset or Continuous) that was in effect
before the manual reset will continue to take effect.
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.
If the folder contains file number 9999, a new folder will be created
automatically when the next image is captured. The image will then be
saved in the new folder as file number 0001.
For both JPEG and RAW images, the file name will start with "IMG_".
The extension will be ".JPG" for JPEG images and ".CR2" for RAW
images.
