How to show preview thumbnail for Illustrator files in Windows Explorer?
How can I make Windows Explorer use preview thumbnails for Illustrator files (*.ai) like Corel files currently do so that my files are easier to identify?
Its possible to do if you have a extension that previews PDF files. Then all you need to do is register the preview for the PDF files to AI files. Now the actual change in registry you have to make may differ depending on your PDF reader but instructions can be found,
