A File Bundle is a collection of individual files, abstracted from whatever media they might
|
|
be one.
|
|
|
|
Initial motivation is allowing some machines direct local filesystem access. An attempt has
|
|
been made to draft this in such a way as to allow it to do things like expose ZIP files as
|
|
bundles in the future.
