Image/Sound File and Folder Names
• Pictmotion movies (c 58) are stored under the "NKST" folder in folders
named with a three-digit folder number followed by "PRJCT" (e.g.,
"101PRJCT"). Each folder contains the picture and sound files for a single
Pictmotion movie.
• Folders can hold up to 200 pictures; if a picture is taken when the current
folder contains 200 pictures, a new folder will be created by adding one to
the current folder number. If a picture is taken when the current folder is
numbered 999 and contains 200 pictures or a picture numbered 9999, no
further pictures can be taken until the medium is formatted (c 115) or a
new memory card inserted.
