If you are a graphic designer or illustrator who wants to export your Illustrator files to Photoshop, there are a few things you need to know. First, Illustrator is a vector-based program, so it is not as powerful as Photoshop when it comes to exporting files. Second, Illustrator files can be quite large and may take some time to export. Third, if you want to use the layers feature in Photoshop, Illustrator will not work with them. Finally, if you want to use the Pathfinder tool in Photoshop, Illustrator will not work with that either.
