How to understand an executable file?

[Jason Long]

Hello,

How can I learn how an executable file work and when open a file in a reverse engineering or debugging tool, understand it?

 

Thank you.

For Documentation on the PE file format (exe/dll):

https://docs.microsoft.com/en-us/windows/win32/debug/pe-format

And something like CFF Explorer:
