Can I timestamp a ZIP file that contains many files? Can I put multiple logos within the same document?
You can timestamp a file containing multiple elements but such an operation provides legal protection for the whole and not for each individual element. If multiple logos are in the same document, you must therefore be sure that none of them is likely to evolve individually. Generally, it is better to timestamp each document, file or creation separately, unless you specifically want to treat them as an inseparable whole.
