Observed behavior
Changes made to a PDF were lost because the file was not saved correctly, potentially due to being opened directly from an email or browser without downloading first.

Recover Unsaved PDF Files After a Crash

If Acrobat closes unexpectedly, use the built-in auto-recovery feature or locate temporary files to retrieve your lost work.

Acrobat has a built-in auto-recovery feature that usually prompts you to restore unsaved documents upon restarting. If this does not happen, you can manually check for temporary backup files on your local drive.

1
Restart Adobe Acrobat

Reopen the Adobe Acrobat application. If the autosave feature was active before the crash, Acrobat will automatically prompt you to open and restore the unsaved file.

2
Locate temporary files

If you are not prompted to recover the file, open File Explorer on Windows and navigate to C:\Users\<YourUsername>\AppData\Roaming\Adobe\Acrobat\DC.

3
Rename and recover the file

Look for temporary files with '.tmp' or '.dat' extensions. Copy these files to your Desktop or a safe folder, rename the extension to '.pdf', and try opening them in Acrobat to see if they contain your lost edits.

Recover Unsaved PDF Files After a Crash
Backup Before Renaming: Always make a copy of the temporary files to another folder before renaming their extensions. Do not rename random system files unless they are clearly identified in the Acrobat directory.

Frequently Asked Questions

Why can't I save a PDF I opened directly from my email?

PDFs opened directly from an email client or web browser are often stored in a read-only, temporary system folder. To save your edits, you must first download the attachment and save it to a local folder (like Desktop or Documents) before opening it in your PDF editor.

Where does Adobe Acrobat store temporary recovery files on Windows?

On Windows, Acrobat typically stores temporary recovery files in the hidden AppData directory. You can find them by navigating to C:\Users\<YourUsername>\AppData\Roaming\Adobe\Acrobat\DC.

Can I recover an unsaved PDF if the autosave feature was disabled?

If autosave was turned off before the application crashed, recovering your unsaved changes is highly unlikely because no temporary backup was created. It is strongly recommended to keep the autosave feature enabled in your Document Preferences to prevent future data loss.
