Bit

Uniform sequence of bits.
Binary data format.

Import can read any file as a sequence of single bits.

Export writes a list of 0s and 1s to a binary file.

IMPORT AND EXPORT

Import imports an arbitrary file as a sequence of bits, returning a packed array of 0s and 1s.

Export exports a list of 0s and 1s to a binary sequence of bits.

Import or Import imports the specified element from file.

Import imports multiple elements.

See the reference pages for full general information on Import and Export.

ImportString and ExportString support the Bit format.

General Import elements:

	"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 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.

Import option:

"HeaderBytes"

0

how many bytes to skip at the beginning of the file
