Did you try to create a new document and File>Place the damamged file in it, to see what may be recovered that way?
Any risk only applies to the file you are changing; you may work on a copy.
Hi Jacob - actually yes I did try that one too. I knew I was missing one! It said it is in a format in which the file cannot be placed.
And thanks I will try to work on a copy from my C drive. I normally work on another drive for artwork like this. I'll see what happens.....ahh
Thank you for your reply too, Jacob. I changed the AI Prefs file and enabled content recovery. I then tried to open the file by starting up Illustrator, going to File>Open>path to file> Select file> Ctrl + Shift + Alt click Open. It still would not open the file, it said the same thing about being an unknown format.
In the Prefs file I have this now:
I saved the file, but took the extension out.
I was not able to do Step 2 from this link: http://kb2.adobe.com/cps/500/cpsid_50032.html
I do not see a recovered file.
I saved the file, but took the extension out.
I am uncertain about this statement.
Another thought: have you tried opening the file in Acrobat (relevant if saved with PDF compatibility, which may rescue a possibly simplified version of the artwork)?
I opened the AI Prefs file in NotePad then I saved it at the Windows XP: C:\Documents and Settings\<user name>\Application Data\Adobe\Adobe Illustrator [version] Settings\en_US\AIPrefs path as a txt file. I then went to this path in Windows Explorer & deleted the .txt extension. The file looks like this "AIPrefs"
without an extension.
I just tried opening the file into Acrobat, but it said Acrobat could not open because it is either not a supported file type or the file has been damaged.
Here is what I did...
I found this link: http://en.allexperts.com/q/Adobe-Illustrator-1027/open-ai-file.htm
I placed the .ai file into InDesign then exported it as an .eps file. It now opens in Illustrator. There are no text boxes, just those blue lines (I don't remember what that is called), but I can edit text.
I saved as a .ai file and it opens.
File recovery is very difficult, and often fails whichever the effort.
Thank you very much!
I faced the same problem. At first I saved in AI format and when I was trying to open it that was showing the problem.
The solution is: Just save the file in EPS format and it is done ! Now it is opening smoothly. Thanks everyone.
The file "Back school.zip" is in an unknown format and cant be opened

Try unzipping it first.
I had a similar problem today, it was on an older file which had come off of an archive, The solution I found was to open the Illustrator file in a text editing program, I checked the header info which indicated that it was originally saved as a CS3 file. I created a new Illustrator document, and saved it as a CS3 file, and compared the header info for both files in a text editor. The corrupted file looked like this:
___i_*UDF Mac ResourceFork____∂___//:+_Äó_13!Saved As v.13 Created by v.13.0.0__//:îÚ3_$__2vers
The newly created file looked like this:
So, I replaced the first 2 likes in the corrupt file with the first line in the other file, and I was able to open the corrupted file.
Mark, if you look closer you can see the correct PDF signature in the third line. This file was probably copied (mailed, zipped) between a Mac and a Windows machine, and the governing software thought it was a good idea to just stick Mac OS X's internal metadata to the start of the file.
If you used a plain text editor, you got very lucky with this one! Most "plain text editors" mess up binary files beyond salvation, and a PDF is a binary file. Worth mentioning because most people won't be that lucky (imaging letting Notepad loose on such a file). Next time, try with a good hex editor.
Also, this is by far not the only thing that can go wrong with a file, and I'd highly recommend to others with damaged files to not try this ... Nevertheless, good save!
Thanks for the extra info, this was a straight Illustrator file, not a PDF. Unless things have changed, they are still text files, correct? Plus, this was on a mac, and I never had a problem before editing them via the standard text edit programs. I don't think I'd try using Notepad, however.
I used to edit the Postscript code for corrupt illustrator files back 20 years or so. I don't recall what was the cause of the corruption, but there used to be better information when opening them (the error dialog would show the offending code, and I could often find that line, and compare to the same line in another similar file). I believe I also used that method to merge custom colors and such before that was possible.
Once, I saw the contents of someone's Apple Menu Items folder listed in the actual postscript code of an Illustrator file. never figured out what happened to cause that to happen.
Yes, I was lucky that it was a quick and easy find, but if it hadn't worked, I would have dug further and possibly found the culprit.
I will look into using a hex editor in the future, though.
