Import/Export Format
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
["
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", {
elem
1
,
elem
2
,
...
}}]
imports multiple elements.
See the reference pages for full general information on
Import
and
Export
.
ImportString
and
ExportString
support the Bit format.
ELEMENTS
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
"Data"
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.
OPTIONS
Import
option:
"HeaderBytes"
0
how many bytes to skip at the beginning of the file

Basic Examples
Convert a text string to a list of bits:
In[1]:=
Out[1]=
Convert a list of 0s and 1s:
In[2]:=
Out[2]=
Export automatically pads with 0s if necessary:
In[3]:=
Out[3]=
