Does a simple recursive binary diff of two directories. Currently supports PE, NE, LE and LX executables.
Windows servicing/Windows Update packages have special support; version numbers and package hashes in directory names are ignored when comparing two extracted Windows Update packages, allowing for comparing cumulative Windows Updates easily.
Intended to easily obtain a list of what executables have changed between two builds of the same software for later bindiffing.
Usage: builddiff path\to\build1 path\to\build2
For each file in the first folder, recursively:
- If it doesn't exist in the second folder, do nothing.
- If the file is not a supported executable, do nothing.
- If the file in the second folder is not in the same executable format, do nothing.
- Compare all text/rodata/data sections of both executables (ignore
.rsrc; zero outIMAGE_EXPORT_DIRECTORY.TimeDateStampand allIMAGE_DEBUG_DIRECTORYblocks in PE; for PE files with bound imports, the IAT is also zeroed). If they are equal, do nothing. - Print the executable type, the filename, the section categories that are different, and a list of section numbers with differences.
For section categories: text means text/code, rdata means read-only data, data means read-write data, sections means section count changed, or section flags changed.
If all sections of an executable are different, then all is printed instead of a list of section numbers.
