It can be done with Windows, but it depends on how you set up and save the file and what version of software you're using. I'm using Illustrator 9 and can view illustrator EPS thumbnails. I'm not sure, but I assume it would work for AI files too.
Most vector clip art is normally saved as an older version of illustrator without the thumbnail option. So, if you resave the file and you select the "include document thumbnail" option, you can view it in explorer's thumbnail view.
I just need to figure out an action that can resave all the clip art I have
Just for kicks and giggles, I tried EPS and AI files and they both work. You have to save them as Illustrator version 7 or newer and include document thumbnail.
See the problem is when you download clipart and only have an eps file to pick from. If you download a few files without stopping and changing the format and naming each you can't preview the image. What a pain.And I am working in Corel.
And thanks for the info I'll try it
I can view a preview in the import window in corel
