If you do dumpbin /header it will give you all 7 section data dumps. .data .idata .rdata .reloc .rsrc .text .textbss
Among this .rsrc and .idata are both content initialized data. These sections are read-only. Then what is the difference between these two? What is the purpose of the .reloc section?
The .rdata section represents read-only data, such as literal strings, constants, and debug directory information.
The .rsrc section contains resource information for a module. It begins with a resource directory structure like most other sections, but this section's data is further structured into a resource tree. The IMAGE_RESOURCE_DIRECTORY, shown below, forms the root and nodes of the tree.
