Use Newer Version of Illustrator Files

Use Adobe Illustrator Files That Have Been Save In A Newer Version Than Your Own.
Often you will be provided with Adobe Illustrator files that were saved in a newer version than the version that you are currently using. Your customers may provide you with Illustrator files that could have come from a different source such as a different designer or
a different branch location and you are unable to have them save it down a version so you can open the file. When you try to open the file you will be faced with the warning message that the file was saved in a newer version. This will happen with both .ai and .eps files.

If the original file was created using some of the special effects and features that exist only in that newer version such as drop shadows, and other special effects it may not render correctly. It is really defendant on what was done with the file and the version of Illustrator used to create the original art work and the version that you have.
