FileInfo unit

File and program version information utilities

The FileInfo unit provides classes and utilities for extracting and manipulating version information from executable files and modules. It includes both low-level access through TVersionInfo and high-level component-based access through TFileVersionInfo.

The unit also provides convenience functions for version comparison (CompareVersionQuads, CompareProgramVersion, NewerVersion), string conversion (VersionQuadToStr, ProgramversionToStr, StrToVersionQuad, StrToProgramVersion), and version extraction (GetProgramVersion).

Classes and records

`EVersionInfo`	class	Exception class for version information errors
`TFileVersionInfo`	class	High-level component for accessing file version information
`TProgramVersion`	record	Record type for storing four-part version numbers
`TVersionInfo`	class	Low-level class for accessing version information from executable files
