The HighEdit document is a proprietary file format generated by the HighEdit Visual Component Library (VCL), a text processing toolset originally developed by Heiler Software. It is primarily used for storing rich text content, including formatting and embedded objects, within specific legacy applications built using the Borland Delphi framework. As an obsolete format rarely encountered in modern computing environments, it serves as a static data container with minimal associated security risks.
