Storing data as Base64 in a big file

[vfclists]

Does the Base64 format allow storing multiple sets of data in a single file?

Does it allow them to be labelled so that you can simple load the item you want by search for hits header, some kind of prefix and suffix the encoded data?

Is there some standard used for this, I am thinking about storing each item on a single line, and prefixing it with a label, so they can be easy to find, even if loaded in a text file?

This is just an encoding, nothing more afaik.
