Finding Illustrator auto-recovery files after crash without saving

You're in the middle of a tight deadline, working on a complex vector illustration with layers, gradients, and custom brushes. Illustrator suddenly freezes. The spinner of death. Then — poof — gone. No prompt to recover. No autosave dialog. The file you've been working on for two hours? It never got a manual save.

What's actually happening here is that Illustrator's auto-recovery system is real-time but fragile. It writes temporary recovery files to a specific folder every few minutes — but only if the file was saved at least once. If you never saved the file at all, the auto-recovery system still works, but the naming convention and location are different, and Illustrator's built-in "recover on launch" often misses them. The real fix is to dig into the hidden recovery folder before Illustrator cleans it up on next launch.

The root cause

Illustrator's auto-recovery is not a save-and-replace system. It writes incremental data to a temp file with a UUID-based name (something like AITEMP_4F3A2B1C.tmp). These files live in a system-level cache directory. The key problem: Illustrator only checks for these files when it detects a clean shutdown didn't happen. But if the crash corrupted the session state, or if you killed the process manually, the recovery prompt doesn't appear. The files are still there — they just aren't linked to any open document record.

Another trigger: if you're on macOS with iCloud Drive or Dropbox syncing enabled, those services sometimes lock the temp directory, causing Illustrator to skip writing the recovery file altogether. That's a separate issue, but worth knowing if you've been bitten before.

Step-by-step recovery

1. Do not relaunch Illustrator yet. If you launch it, it may clean up old temp files. Work from Finder (macOS) or File Explorer (Windows) first.
2. Navigate to the auto-recovery folder:
   • Windows 10/11: %APPDATA%\Adobe\Adobe Illustrator [version] Settings\en_US\x64\DataRecovery
     Example for Illustrator 2024: C:\Users\YourName\AppData\Roaming\Adobe\Adobe Illustrator 28 Settings\en_US\x64\DataRecovery
   • macOS: ~/Library/Application Support/Adobe/Adobe Illustrator [version]/en_US/DataRecovery
     Example: /Users/YourName/Library/Application Support/Adobe/Adobe Illustrator 28/en_US/DataRecovery

   Note: The version number matters. Illustrator 2023 is version 27, 2024 is version 28, 2025 will be version 29. If you're not sure, check the folder name that has the highest number — that's your active install.

3. Sort by date modified. Look for files with .tmp or .ait extensions that were created around the time of the crash. The file size should be large (megabytes, not kilobytes).
4. Copy those files to a safe location — your desktop works. Never work directly inside the DataRecovery folder; Illustrator may delete them during a future launch.
5. Rename the file extension to .ai. So AITEMP_4F3A2B1C.tmp becomes myrecovered.ai.
6. Open in Illustrator. If it opens, immediately use File > Save As to save it properly. If Illustrator says the file is corrupted, try opening it with File > Open and check "Recover" in the dialog (if available).
7. No luck? Try the legacy recovery path. Some Illustrator versions also drop files in %TEMP%\Adobe Illustrator [version] (Windows) or ~/Library/Caches/com.adobe.illustrator-[version] (macOS). Same drill — look for large .tmp files and rename them.

What if the files aren't there?

If the DataRecovery folder is empty or only has tiny files (under 1KB), Illustrator didn't write a recovery point. This happens when:

• You were working for less than 2 minutes since last auto-save interval (default is 5 minutes, but can be changed in Preferences > File Handling & Clipboard > Auto-save every N minutes).
• The crash corrupted the temp file before it was flushed to disk — especially common with memory-related crashes on large files over 500MB.
• You have third-party security software that blocks writes to AppData — check your antivirus logs.

In that case, you're out of luck for auto-recovery. Your only other option is checking the %TEMP% folder for any Illustrator-related scratch files (they'll have .tmp and might contain partial data), but that's a long shot. I've recovered usable data maybe 1 in 10 times with that method.

Final opinionated advice: Change your auto-save interval to 2 minutes in Preferences. Yes, it causes a tiny performance hitch every 2 minutes on big files. The alternative is redoing two hours of work. Pick your poison.
