We'll ask for a compressed, zipped folder. You can include pdf, jpeg, png, tiff or native files from photoshop, indesign or illustrator. All files should be already laid out and named with where they should be placed in the template.
Locate the file or folder that you want to zip.
Press and hold (or right-click) the file or folder, select (or point to) Send to, and then select Compressed (zipped) folder.
A new zipped folder with the same name is created in the same location.
To rename it, press and hold (or right-click) the folder, select Rename, and then type the new name.
Regardless of which type of files you'll be uploading, select Native Files and then upload.
