Check for zipped file name-unzip to different directory-rename files sequentially-copy all files to final directory

Your software would need to check a directory for zipped file names meeting a certain criteria. If they exist, we need to unzip them and copy the extracted files to a second directory (where other extracted files may exist) and delete the zip. Finally, we copy all the files in directory 2 over to directory while verifying that files of the same name have never been copied to directory 3 before. I need to have a settings area where I can enter the locations of the 3 directories. Attached, please find a [login to view URL] with more detailed information as well as a copy of the software we presently use. The old software does not have unzip function (or 3rd directory). The old software renamed files sequentially, but that is no longer necessary. Software needs to run on XP, and 2003, 2008 servers. The attached software worked fine for years until our new vendor began placing files in different directories, some zipped and some not.
