It combined 129 .pdf files totaling 315 pages. Just un-rar with 7-zip, look into bin->release->PDF Merger.exe or bin->debug->PDF Merger.exe. Note that the default settings are to encrypt the file with some 3-character password (just delete this to not protect the created file with a password), also, it prints page numbers on each page by default. Furthermore, it tries to put a watermark on the created file by default. I disabled all of these and can only attest to the accuracy of the page numbers. Beware that the 'clear selected' and 'clear all' buttons have switched functionality. To open the file once it has been created (without trudging through a file directory), click near the bottom of the GUI. Even though it looks like a burden, it combined the .pdf files as needed (note that any linking between the .pdfs are not preserved once the files are combined into the one file). A big thanks to those responsible for this program.
