File and Folder Names
• A single folder can hold up to 200 pictures; if the current folder already contains
200 pictures, a new folder, named by adding one to the current folder name, will
be created the next time a picture is taken. If the current folder is numbered 999
and contains 200 pictures, or a picture is numbered 9999, no further pictures can
be taken until the internal memory or memory card is formatted (A147), or a
new memory card is inserted.
