MATHEMATICA IMPORT/EXPORT FORMAT

Bit

Uniform sequence of bits.
Binary data format.

Import and Export Import and Export

Import["file", "Bit"] imports an arbitrary file as a sequence of bits, returning a packed array of 0s and 1s.
Export["file", list, "Bit"] exports a list of 0s and 1s to a binary sequence of bits.
Import["file", {"Bit", elem}] or Import["file", elem ] imports the specified element from file.
Import["file", {"Bit", {elem₁, elem₂, ...}}] imports multiple elements.
See the reference pages for full general information on Import and Export.
ImportString and ExportString support the Bit format.

	"Elements"	elements and options available in this file
	"Rules"	full rules for each element and option
	"Options"	rules for options, properties, and settings

Data representation element:
"Data" list of single bits (0 or 1)
By default, Import and Export use the element.
Import["file", {"Bit", n}] gives the n bit from file.
Export["file", list, "Bit"] pads list with zeros at the end if the number of bits to be exported is not a multiple of 8.
