How i can publish more than one file in a single product?

I put all my files in a zip file and I think some other sellers do this.

Seth to upload more than one file you dont need to have it in a .zip, its optional file you just drag the files no matter the type of it and cg trader recognizes the file, hope this help you

You should be able to just drag and drop them into your desired folder but if that doesn't work you can zip them although that makes it more complex for you customers to just download the specific file they want. They have to have to go through the extra step of downloading and then unzipping your files before using them. Also be sure to check if the files unzip correctly before you upload them. More often then not it has happened that when you zip files they get corrupted in the process and then you get complaints from customers who were not able to open the file.

Thanks every one for your answers, it really helpful=) Well, if zip archive is complicated for customers, than it truly have a sense to upload it without archivation, but problem is, when i am trying upload textures, images in obj format, cgtrader upload it as a preview image, not like other files to download. And thanks again for your answers=)
