So this morning I was finishing up a design I was working on before heading into work and I hit save to save the file to my HD and then being in a rush I didn't realize it was taking a moment to make the save. So I shut the computer off and when I got into the office much to my surprise the file said "Photoshop unexpected end of file error" and I was freaking out. How can I get my 200 layer PSD back open. So, I searched the forums and most people said I was screwed. This problem is caused when photoshop doesn't complete writing the headers and footers of the file. They said on average it happens once a week and the files are just lost. We'll I had a crafty spark of geniousness and I thought I wonder if Illustrator can open this file. So I dragged it on the icon and Bam! Illustrator CS3 opened the file just fine and kept the layers. Also I was able to export the file from there and save it as a PSD with all my layers. I gave it a different name to be safe and there it was on the desktop. Then I opened it in Photoshop and boom! It worked just fine and kept all the layers. Yeah! So, I'm not sure if this will always work or if this is a new feature with CS3 but it saved my day.
