H4download - 'link'.h

Header files, denoted by the .h or .hpp extension, are used in C and C++ programming (and potentially in other languages) to declare functions, variables, and macros that can be used across multiple source files. They serve as an interface to the functionalities implemented in source files ( .c or .cpp files), allowing for code reuse and modularity.

Unrecognized header files with generic “download” names sometimes appear in malicious code repositories or cracked software. h4download.h
