I will give you a detailed explanation of the reason why the file cannot be read and the solution.
Overview:
1. Memory error. Turn off AI and open the file again. // I tried it and it is invalid for my file.
2. Restart the computer and re-open the file. // restart the computer to release the memory occupied by the system. Sometimes the computer has been used for a long time and the memory is heavily occupied, it is easy to open the aifile. Restarting may solve the problem.
3. File corruption (transmission or copy damage), and then ask the customer for. // This is basically not a solution.
4. I have received an aifile possibly made by a foreigner. The link graph is not only large, but also has many layers-hidden layers, Text layers, and shape layers, there are also redundant paths, redundant channels, and specialized channels ......
Once this aifile is opened, the file cannot be read!
Open all links, delete hidden layers, redundant paths, redundant channels, and merge visible layers ...... However, the file is still unreadable!
As a result, if there is a problem with the link file of the aifile, it will show that the file is unreadable!
So open all the link diagrams again, save the tif format to the new folder, and copy the aifile to the new folder and re-open it. Because the link diagram format is changed, the system prompts that the link graph is missing -- ignore here -- apply to all --
When the AI file is opened, the link is updated for each link graph. Some links are shown as "the file is unreadable !"
Why can't the PSD link graph save tif still be unreadable? Deeply shocked! Because the hidden layers, redundant paths, and redundant channels have been deleted before -- and the visible layers have been merged -- helpless, and only other formats can be saved -- the final result is found, save Photoshop pdf with a transparent link graph (select the storage transparency check box) to smoothly insert Illustrator. Save Photoshop eps without transparency can also be smoothly inserted into Illustrator. Now, the file problem is solved.
5. I have processed a set of ai-based versions. It is normal for a single file. When you splice the same content into a multi-mode, save it, the next time you open the file again, you will be prompted that the file cannot be read, and then the file cannot be opened. This should also be the reason for the system memory. After all, too many items have high requirements on the processing capability of the software, in this case, it is best to link the same image in the file (do not embed it, and try to make the linked image as concise as possible: refer to Article 4 above)
This may occur when too many connected image files are too large, which is related to the memory size.
Solution: remove the image, ignore the link when it is opened, split the file into several files, and then move the image back. In this way, the number of images linked to a file is reduced and can be opened easily.
6. When I opened a file with Illustrator CS5, I encountered the "file unreadable" prompt. I suddenly thought that Illustrator cs6 had a qualitative change in the file processing speed, so I used Illustrator cs6 to open the file. Haha, the file is not readable. In the future, if the aifile cannot be read, you can try it with the advanced version of Illustrator.
All right, the above information is the detailed reason why the file is not readable for the users of Illustrator's software and the solution to resolve all the content shared, you can see the users here. I believe you are very clear about it now. I hope the information above will help you.
