Canon PowerShot SX420 IS Owner's Manual

110

Your shots are automatically numbered in sequential order (0001 – 9999) 

and saved in folders that store up to 2,000 images each. You can change 

how the camera assigns file numbers.

 

●

Choose [File Numbering], and then 

choose an option.

Continuous

Images are numbered consecutively (until the 

9999th shot is taken/saved) even if you switch 

memory cards.

Auto Reset

Image numbering is reset to 0001 if you switch 

memory cards, or when a new folder is created.

 

●

Regardless of the option selected in this setting, shots may be 
numbered consecutively after the last number of existing images 
on newly inserted memory cards. To start saving shots from 0001, 
use an empty (or formatted, = 109) memory card.

 

●

The total card capacity indicated on the formatting screen may be 
less than the advertised capacity.

Perform low-level formatting in the following cases: [Memory card error] is 

displayed, the camera is not working correctly, card image reading/writing 

is slower, continuous shooting is slower, or movie recording suddenly 

stops. Low-level formatting erases all data on a memory card. Before low-

level formatting, copy images on the memory card to a computer, or take 

other steps to back them up.

 

●

On the screen in step 2 of “Formatting 

[ ][ ] buttons to choose [Low Level 

Format], and then press the [ ][ ] 

buttons to select this option. A [ ] icon is 

displayed.

 

●

Follow steps 2 – 3 in “Formatting Memory 

Cards” (= 109) to continue with the 

formatting process.

 

●

Low-level formatting takes longer than “Formatting Memory 
Cards” (= 109), because data is erased from all storage regions 
of the memory card.

 

●

You can cancel low-level formatting in progress by choosing 
[Stop]. In this case, all data will be erased, but the memory card 
can be used normally.
