Common I/O Tasks
The xtd.io namespace provides several classes that allow for various actions, such as reading and writing, to be performed on files, directories, and streams. For more information, see File and Stream I/O.
​
Preamble
Prefer in your application to use the Input/output library and Filesystem library of the std.
xtd has its own IO API because the Filesystem library doesn't work on all OS (like for example iOS).
Some features exist only in the xtd API like binary reader/writer, stream reader/writer, string reader/writer and text reader/writer.
