QuickReport Report file (QRP) is a proprietary document format developed by QuSoft for use within the Delphi and C++Builder integrated development environments. It is primarily used to store pre-rendered report snapshots, enabling users to view, archive, or print complex data layouts without reconnecting to the original database. Considered a legacy format today, QRP files are inherently safe as they contain static graphical data rather than executable code or embedded macros.
