There are a few things you can do to help save vector files in Photoshop. The first is to make sure that the file is properly named. If it isn’t, Photoshop will automatically fill in the name for you. You can also choose to have Photoshop create a new file for each object you add, or to keep all the files together in one place. Finally, if you want to keep your vector files as large as possible, try using the “max size” option when creating them.
