Read in an image file as a byte array:

The byte array contains the contents of the file for further manipulation:

Export text to a file:

Read in the file as a byte array:

View the individual bytes:

Convert the bytes back to a string:

Read in a WXF file:

Read in the file, explicitly specifying the EndOfFile terminator:

Convert the data to expressions:

Read in the first line of text of Alice in Wonderland as an array of bytes:

Read the next line of text:

Close the file:

Read the first 70 bytes of the United States Constitution:

Convert the bytes to text:

Read until either 70 bytes have been read or an end of line is encountered:

Repeat the process:

Close the file:

Open a system shell using StartProcess:

Clear out any welcome text:

Write a command to the process that generates output:

Read the available output as a byte array:

Convert the bytes to a string and notice that it includes the end-of-line character:

Write the command to the process a second time:

This time, read until the end of line is reached:

The byte array no longer encodes an end of line:

Kill the process:

Open a socket connection:

Write a request to the socket:

Read until the byte sequence corresponding to GIF89 is read:

Convert the data in the HTTP header to text:

Read all remaining bytes:

Join the bytes with the GIF header and import the images:

Close the socket:

ReadByteArray[src] is effectively equivalent to ByteArray[BinaryReadList[src]]:

ReadByteArray[src] is effectively equivalent to StringToByteArray[ReadString[src], "ISO8859-1"]:

ReadByteArray[src,n] reads n bytes at once:

BinaryRead[src] reads one byte at a time:

The data is the same as read in by ReadByteArray:

Close the stream:

ReadByteArray[src] is effectively equivalent to StringToByteArray[Import[src,"String"],"ISO8859-1"]:

ImportByteArray[ReadByteArray[src]] is effectively equivalent to Import[src]:
