Files
A file is a sequence of bytes stored on the computer
Each byte is made up of 8 bits
An ASCII character is one way of storing letters.
“Plain text files” often use ANSI ASCII encoding.
To encode other languages, we need to use a different encoding.

Using files in Java
Both files and folders (Directories) are represented with a “File” object.
We can open the file to get the byte stream
(Coding example)
File file = new File();
boolean isDir = file.isDirectory();
