• Files copied using Copy>Selected images are copied to the current folder, where they
are assigned new file numbers in ascending order starting from the largest file number in
memory. Copy>All images copies all folders from the source medium; file names do not
change but new folder numbers are assigned in ascending order, starting from the largest
folder number on the destination medium (E61).
• A single folder can hold up to 200 files; if the current folder already contains 200 files, a new
folder, named by adding one to the current folder name, will be created the next time a file
is stored. If the current folder is numbered 999 and contains 200 files, or a file is numbered
9999, no further files can be stored until the internal memory or memory card is formatted
(E80), or a new memory card is inserted.
