I have really old iullsutrator files I was hoping to take a look at (illustrator 88). Is there any hope?
Yes, make sure they have the .ai extension or open them from the Illustrator File > Open dialog.
Thanks for reaching out. In addition to the earlier suggestion, I'd request you to check out this help article to know the supported file formats in Adobe Illustrator. Hope it helps.
Thanks, I may be working with a currupted file but none of the ideas presented so far seem to work. I know there are soem 3rd party apps that may help, any insights to those?
Try opening them in Adobe Acrobat or Acrobat Distiller. You could also try sharing the files here and seeing if anyone of us can open them.
You can try to open them in a text editor and see if they start with %!PS-Adobe-2.0 EPSF-1.2
