PDFs can be difficult to ungroup. They can be made up of many different files, and it can be hard to tell which file is the main document. In Illustrator, there are a few ways to help ungroup PDFs. The first way is to use the Group tool. This tool will group all of the files in a pdf into one big document. The Group tool is great for unifying a pdf into one big document, but it can also be used for other tasks such as creating lists or tables. The second way to help ungroup PDFs is by using the Selection tool. This tool will allow you to select only a small part of a pdf. This will help you group all of the files together, but it may not work for all pdfs. The third way to help ungroup PDFs is by using the Pathfinder feature in Illustrator. This feature will allow you to move around the files in your pdf while they are still being processed by Illustrator. This will help you group them together better and make it easier to see which file is the main document.
