What An Executable File Imports

Import ViewerImports are functions used by one program to link to code libraries the contains the required functionality and are stored in different programs.

The EXE Import Viewer presents details about the linked libraries, showcasing the list of functions that the executable file imports, and the specific Dynamic Link Libraries (DLLs) from which the program imports these functions. This information is essential for understanding how a program interacts with external code and libraries to achieve its required functionality.

Retrieve the List of Imported Functions

When the program file is loaded, the operating system finds a table of data in the file which contains the list of functions the program is going to use from the DLL. It uses the information to search the DLLs for the addresses of the functions to be patched into the main program. Names of these Windows functions can give you a proper idea of what the executable does.
