Delphi TStream-based APIs handle binary and text I/O by transferring data between TFileStream and TMemoryStream. You read bytes into memory streams from files and write them back, applying encoding handling and serialization templates for structured data operations.

Text encoding in Delphi RTL streams is managed using TEncoding with BOM detection for cross-platform compatibility. When reading text via TStream or TIOUtils, you detect the byte order mark to correctly decode UTF-8 or UTF-16 text data into strings.

TIOUtils and TPath/TFile/TDirectory support cross-platform file operations in Delphi RTL. You can read, write, and manage files across Windows and macOS using these APIs, ensuring consistent path handling and stream-based data ingestion.

Inter-stream data transfer in Delphi copies bytes directly between TStream instances like TFileStream and TMemoryStream. Binary serialization templates structure this data, allowing you to serialize objects or binary payloads into a target stream with encoding conversion applied.

Compression and serialization templates extend Delphi stream I/O by reducing data size and structuring binary payloads. While basic TFileStream reading and writing does not require them, they are necessary for efficient file ingestion and inter-stream data transfer of complex objects.
