1. How to Recover Unsaved Adobe Acrobat Files
To prevent users from data loss, Adobe developed a protection feature called Autosave. This feature is enabled in Acrobat by default. It saves a file of changes every few minutes, generally, it's five minutes. To check the Autosave status, you need to open the application and click Edit > Preferences, then click Documents and head to Save settings. You can change the save time by checking the "Automatically save document changes to temporary file every X minutes" option. Then Acrobat will generate a temporary file every few minutes. Once the Adobe Acrobat gets crashed, it automatically opens the auto-saved PDF file when you relaunch the software.
If your PDF files do not appear, there's another way for you to try to restore the files manually. Under this condition, you need to find where are the Adobe Acrobat temporary files stored on your computer. You can find the answer in the following steps.
Step 1. Go to the following path on your computer, that's where the Acrobat temporary files are:
C:\Users\username\AppData\Roaming\Adobe\Acrobat\DC
If you are using the Adobe Reader, then go to:
C:\Users\username\AppData\Local\Temp\Adobe\Reader\11.0
Step 2. Find the temporary files in the above location, copy and paste these files to another location.
- Notice:
- The extension of these temporary files may not be the same as the original ones. It could be *.dat files or *.tmp files.
Step 3. Change the extension of the copied temporary files as *.pdf.
Step 4. Try to open the temporary files with Adobe Acrobat.
According to Adobe support, the temporary file is deleted if you close the Adobe Acrobat (whether you save or not). The only purpose of the temporary saves is to recover if Acrobat or computer crashes, power cut, etc. So if you didn't encounter a software or computer crash, you might not be able to recover unsaved Adobe Acrobat files through temporary files.
