I am having trouble understanding the compression format of a multi-page dwf.
I basically need to update a page from time to time without having to regenerate the entire file.
I can read the dwf contents and update a file using winzip if it was created using mergefiles.
However, if use winzip to create a new archive (and the rename it to dwf), I get error messages that say the file is not a dwf.
does anyone know what the difference is. why does winzip save an existing file correctly but not a new one.
