How to Repair Illustrator File in 5 Ways [2026]

Part 1. Why is My Illustrator File Corrupted/Not Opening?

• Sudden Crash: If Illustrator crashes suddenly while you are working on it, the working file can get damaged.
• Sudden Shut Down: A sudden computer shutdown due to power cuts can corrupt your Illustrator working files, making them unopenable.
• Disk Space Shortage: Insufficient disk space can prevent Illustrator from functioning correctly and may lead to file corruption.
• Transfer Interruption: If you are transferring AI files from your USB drive to your local drive and the process gets interrupted in the middle, the AI files can get corrupted.
• Incompatibility: Attempting to open an AI file created with a newer version of Illustrator when you have an older version can result in compatibility issues. Illustrator may indicate that the file is damaged due to this incompatibility.

Here are the steps to fix Illustrator file not opening via Illustrator’s content recovery mode.

Note:

You should create a backup of the Illustrator file before proceeding.

• Ensure Illustrator is not running on your computer. Then navigate to the following address to reach the Adobe Illustrator Prefs file.

  • Windows: C:\Users\\AppData\Roaming\Adobe\Adobe Illustrator Settings\en_US\x64\Adobe Illustrator Prefs.
  • macOS: /Users//Library/Preferences/Adobe Illustrator Settings/en_US/Adobe Illustrator Prefs.
• Open the Adobe Illustrator Prefs file in Notepad (Windows) or Text Edit (macOS).

• Search for “enableContentRecovery” keyword in the file. You will find the value of “enableContentRecovery” as 0. You need to change that to 1. In case you do not find an “enableContentRecovery” configuration entry, add “/enableContentRecovery 1”.

  
• Save the modified Prefs file, keeping the same extension as the original.
• Open Adobe Illustrator. Go to File> Open. Select and highlight the corrupted AI file that you want to repair but do not open it.
• Press Ctrl + Alt + Shift keys together. For macOS users, press Cmd + Opt + Shift keys together. Click on the Open option while holding down the keys.
• A blank document will open. Close the document, but do not save it.
• Navigate to the folder where the corrupted file resides. Look for the duplicate copy of the corrupted file with an underscore in the beginning, and that is the repaired file. For example, if the corrupted file is “MyAiFile.ai” then the repaired file should be “_MyAiFile.ai” in the same folder.

Note:

You might lose some data in your AI file in this method as it eradicated the corrupted data to repair the file.

Method 3. Change the Extension to .pdf from .ai

Many users have reported that converting the corrupted AI file to a PDF file first and re-converting the PDF file to AI file has repaired the file successfully.

Here are the steps to follow.

• Launch Adobe Illustrator and open the affected corrupted AI file.
• Go to File> Save A Copy.

• In the Save dialog box, select the file format as “Adobe PDF.”

  

• Click Save and configure the PDF settings and options as needed. Once done, click Save PDF and your AI file will be saved as a PDF.

  
• Close and relaunch Adobe Illustrator. Open the saved PDF file.

• Go to File> Save As and choose the AI file format. Following this, click the “Save” button at the end.

  

This should repair the file, and you can edit the designs in the file on Illustrator now.
