How to Recover Unsaved Adobe Acrobat Files via Adobe Autosave?

To help prevent data loss, Adobe Acrobat includes a built-in AutoSave feature that is enabled by default in most cases.

• Reopen Adobe Acrobat after a crash or unexpected closure.
• Look for the Document Recovery window that appears automatically. This window lists any files that can be recovered.
• Select the file you want to recover from the list. Open it and immediately save it to a secure location with a new name.

This method is especially useful when Adobe Acrobat crashes or a PDF is closed unexpectedly without saving. It is the most straightforward way to recover your recover unsaved PDF in Adobe Acrobat. If your file is not listed, you can try manually recovering the file by locating the AutoSave temporary files in the designated folder.

How to Recover Unsaved PDF via Adobe Acrobat Temporary Files?

If the Document Recovery window doesn’t show up, you can still recover your unsaved Adobe PDF by checking Adobe Acrobat temporary files. Knowing where Adobe saves temp files is key, because Acrobat stores backup copies there that can be used to restore your work after a crash, unexpected closure, or accidental loss.

Here's how to recover unsaved PDF from Adobe using temporary files:

• Open Adobe Acrobat and go to "Edit → Preferences → Documents".
• Find "Automatically save document changes" and note the AutoSave file location. (If you cannot find the AutoSave folder through Acrobat, you can manually check common locations:)
C:\Users\username\AppData\Roaming\Adobe\Acrobat\DC
C:\Users\username\AppData\Local\Temp\Adobe\Reader\11.0
• Open File Explorer (Windows) or Finder (Mac) and navigate to that location.
• Look for files starting with "~", ending with ".autosave", or using extensions like *.tmp or *.dat.
  
• Copy the temporary files to another safe folder, then rename the copied file extension to .pdf.
• Try to open the temporary files with Adobe Acrobat.

Notes

Recovering unsaved Adobe Acrobat files via temporary files works best after a crash, power outage, or unexpected system shutdown. According to Adobe support, temporary files are designed only for emergency recovery and are usually deleted when Acrobat is closed normally, whether the file is saved or not. That means you may not be able to restore an unsaved PDF through temporary files if no crash or abnormal closure occurred.

How to Recover Adobe Acrobat Files After Crash?

Sometimes a PDF file cannot be opened not because the file itself is corrupted, but because the Adobe Acrobat application is damaged. In such cases, repairing the Acrobat software is necessary to resolve the issue. The following are some common ways to fix a damaged PDF application.

Method 1: Fresh Start Adobe

First, press Windows + X to choose and open the Task Manager and close all running Adobe processes. Then, restart Adobe Acrobat. This simple step can resolve minor glitches and conflicts caused by leftover processes running in the background, allowing the application to function properly.

Method 2: Check for Updates

If the PDF files won’t open, the issue may be due to using an outdated version of the software. Keeping Acrobat up to date can ensure compatibility with the latest PDF features. To check for updates, you need to open Adobe Acrobat, go to "Help → Check for Updates". Once the update is installed, restart Acrobat and try opening your PDF again.

Method 3: Reinstall Adobe

If updating Adobe Acrobat doesn’t fix the problem, the issue may be caused by a corrupted or incomplete installation. To resolve this, you can reinstall Adobe Acrobat.

Go to "Settings → Apps → Apps & features", find Adobe Acrobat, and click "Uninstall". One uninstalled, you can download the latest version from the official Adobe website. Install and launch the software, and open your PDF files to check if the issue is resolved.

Method 4: Run Adobe Acrobat as an Administrator

Sometimes Adobe Acrobat may not have the necessary permissions to access certain files or system resources, which can prevent PDFs from opening.

Running Acrobat as administrator ensures the program has full access to your system, which can resolve permission-related issues and improve stability.

Right-click Adobe Acrobat and select "Run as administrator". To make this the default setting, right-click the Adobe icon, select "Properties → Shortcut → Advanced", and then check “Run as administrator.”

Method 5: Use Compatibility Mode

If Adobe Acrobat is still having trouble opening PDFs, the issue might be related to compatibility with your operating system. Using Compatibility Mode allows the program to run as if it were on an earlier version of Windows, which can resolve crashes, freezes, or other unexpected errors.

To run Adobe Acrobat in Compatibility Mode, start by right-clicking the Adobe Acrobat shortcut and select "Properties". Then, go to the "Compatibility" tab. Check the option “Run this program in compatibility mode for:” and choose an earlier version of Windows from the dropdown menu.
