Your .exe files are self-extracting archives for Windows. If they are self-extracting .zip archives, then Stuffit Expander and other decompression utilities on the Mac can handle them. You may try to decompress the file using the Finder's built-in unzipping utility, but I have no idea if it will work.... I am trying to deal with a large company for materials orders. They supply their catalogues as exe files, .... How can I open these files? ...
Right. Some .exe files are actually compressed ZIP files that can be uncompressed on systems that do not have any kind of zip uncompression software installed -- hence, them being called "self-extracting archives."There is no .zip or any other compression noted. It is just a straight .exe file.
