Hi! I've got a relatively small illustrator file that when I open with the latest version of Illustrator CC is coming up with "Acrobat PDF File Format is having difficulties. Expected dict object". I think it has corrupted and I do not have a back up of this file. I was working from a WD external hard drive at the time. The file looks to still contain data e.g. 2225KB. From opening it in a txt file it looks like end of the file hasnt saved e.g. missing this chunk of code (see bottom of post). I have tried to take this example code from a clean illustrator and copy across to a copy of the corrupted file but not had any luck. Also tried placing the illustrator in clean illustrator files etc. I can still see the raster image preview of the data and can see from the txt editor that there still looks to be some of the data there. If there is any chance someone could help recover this I would greatly appreciate it!

An AI file most of the time consists of two forks: an AIfork and a PDF fork. In your case the PDF fork seems corrupt, so placing in a new AI file won't work.

You could try and open it in Acrobat, perhaps it can repair the PDF part. This won't give you back the AI part. Also: do this with a duplicate of the file.

 

You can also try and send it to ShareWithAi@adobe.com for investigation. Please include a link to this thread.

Hi Monika, thank you for replying! I tried opening thorugh Acrobat but no success. I've sent a version of it to file@adobe.co.uk but in the mean time I'll just start rebuilding the file. 

 

Thanks for your advice!

Following your Google Drive download link I get a message that the access to the file is denied. That means it is not possible to download it.

 

Google recently changed the default options when releasing download links. They are not public by default anymore and you have to deliberately choose the appropriate option to make it available for anyone who knows the download link.
