- TWAIN.PAS is an import unit for the TWAIN functions in twain_32.dll
- RICHOLE.PAS is an import unit for the IRichEditOle Interface
MultiLanguage_tlb.pas is an import unit for MULTLANG.DLL
GraphFlip contains simple functions to quickly rotate 24bpp bitmaps.
unitExGraphics contains SystemPalette2 - a simple black and white palette, and SystemPalette256 - a web compatible 256 colour palette. It also contains the iHLSToRGB function for converting colour formats.

unitCharsetMap contains functions for obtaining font charset and codepage information from ISO charset strings

- TExRegistry, derived from TRegistry provides additional registry handling capabilities, including support for Multi String values, and importing and exporting regedit compatible .REG files
- TVirtualMemoryStream derived from TCustomMemoryStream allows you to reserve contiguous blocks of memory.
- unitMIDIGlobals contains constants, type definitions and low level functions useful for manipulating MIDI data
- TMidiTrackStream is derived from TVirtualMemoryStream and allows you to load and save track information from MIDI files.
- TVersionInfo allows you to access details held in Version Info resources from your programs
- TObjectCache allows you to store objects in a fixed-length cache
- TStreamTextReader allows you to treat streams like a text file
- TGoogleLikeStringSearcher allows you to search strings using Google-style expressions
- TTextFileReader is a fast text file reader.
- TBTree is a disk-based B-Tree index which associates an integer value with a variable length string. Supports strings up to about 2000 characters. Also allows sorted sequential access of strings and their associated integers.
- TDataTree is a disk-based B-Tree index which associates a variable length string value with an integer.
- TIndexTree is a disk-based B-Tree index which associates an integer value with another integer value - effectively providing a sparse array of integers.
- TBTreeIterator is a support class that allows you to quickly iterate through a TBTree
- TDataTreeIterator is a support class that allows you to quickly iterate through a TDataTree.
- TParser is a base class for syntax parsers
- TCPreProcessor is a 'C' language pre-processor, derived from the TParser class
