My computer froze with my illustrator file open. I was able to re-start my computer with no problems. But when I went to open my .ai file -that I have been working on for weeks- it would not open and the tiny window reading "The file xxxxx.ai is in an unknown format and cannot be opened!"
Okay, I don't know what happened. I had saved the file way before the freeze happened. I really need to get into this file. I would hate to have to start from the beginning all over again. I have an older version of illustrator (11.0.0) in Adobe CS. There were no pictures placed onto the file. Its all a vector file. Can anyone please tell me how I can fix this problem?
Try to place the file in a new document, then expand it. If you used auto-save, you may also have this file somewhere (eitehr in the same directory as the main file or your user home directory of your operating system) And don't take this the wrong way, "working on this file for weeks" without having a backup or a version file_0000 to file_0999 to go back doesn't sound like a clever or efficient way to work....
Yes, I am well aware that not having a backup file on this was a bad move on my part, normally I do. Thank you for your candor. Illustrator 11.0.0 for Adobe Creative Suite (not to be confused with the 2,3 or 4 suites) doesn't appear to have auto-save. I know that the Photoshop version 8.0 that came with it does, but not the illustrator. I have tried placing the file into another document, it won't work that way either. You have mentioned two directories. I have no idea on how to access them. But, I am gathering it won't do me any good if auto-save was not used? If they could still help, is it possible that you could please walk me thru it?
Thanks for your help.
You may follow the instructions here: http://kb2.adobe.com/cps/500/cpsid_50032.html ,
to see how the file code starts, both in the sick document and in a healthy document, and then replace the sick code at the start of the former with healthy code from the latter. This may enable you to save all or part of the artwork.
You may post some of the code here for further suggestions.
Thank you for the tip. I still could not open the illustrator file even after I changed the "Content Recovery" from 0 to 1. I was able to open the file in a text only format and found that all of the "pdf" information was gone, as was all of the rest of the information that was needed (I did compare it to a healthy file). Not sure why all of this was wiped out in the first place. I have had my computer freeze on me before with a file open, and when I rebooted my computer and started the app back up with the file I had been previously working on it would always open with no problems (with back up file on hand!). I guess I will just have to chalk it up to a lesson learned.
Thanks everyone for your help!
Yes I have to say though you did not have a back up file it would be good if illustrator came up with a recovery scheme such as ID.
This happens so often and it is easy for someone to get immersed in their work not to back it up on occasion.
We all feel for you.
But make a feature request.
For repair illustrator files use how to recover damaged illustrator files. The program works under Windows 98 and higher. The utility restores .ai files after hdd failures, hacker attacks, malicious software. The tool uses contemporary ways of repairing illustrator info.
