Can multiple base64 documents be stored in a single file?

If files are converted to base64 format can they be put in a single file?

Is 开发者_JS百科there a way they can be prefixed and postfixed in the file to allow them to be extracted?

Yes, of course you can. They are just strings (and a subset at that). Choose any delimiter that is not part of your Base64 encoding (for example, "$"), and concatenate to your heart's content.
