Adobe Acrobat is an application developed by Adobe Inc. for users to view, create, and edit PDF files. PDF stands for Portable Document Format, and it is one of the most common document formats in the world. Many individuals and organizations would use Adobe Acrobat to make resumes, brochures, and specifications in PDF form.
If you have closed Adobe Acrobat without saving or going through a software crash while editing a PDF file, you may want to know if it is recoverable. Luckily, the answer is Yes. You can try to recover unsaved Adobe Acrobat files with the Adobe Autosave feature. You can also recover PDF files through Adobe apps and EaseUS Data Recovery Wizard if you have saved them before but lost them due to a misoperation or virus attack. Please keep reading and learn more about PDF file recovery.
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, 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 Adobe Acrobat crashes, 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:
If you are using Adobe Reader, then go to:
Step 2. Find the temporary files in the above location, and copy and paste these files to another location.
- 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 Adobe Acrobat (whether you save it 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.
In addition to unsaved PDF files, another common data loss situation is that users lose saved files after system updates or virus attacks. Worse still, your files may be corrupted. If you find your PDF files are under the following conditions, then these files might get damaged.
- PDF file not readable
- The root object is invalid or missing
- Error opening document
- File damage or corrupt
- The viewer can't open it
- Error processing page
If you are stuck in this dilemma, please do not perform any operations that may cause file overwriting. Then check your Recycle bin to see if your lost files are in it. If the answer is negative, it is highly recommended you take advantage of data recovery software to recover the files.
EaseUS Data Recovery Wizard works well in many data loss scenarios. It supports users in recovering data deleted by antivirus, recovering files from formatted hard drives, recovering deleted files from the recycle bin, etc. EaseUS Data Recovery software can recover lost or corrupted PDF files in three steps.

This article is mainly talking about how to recover unsaved Adobe Acrobat files. But Acrobat is not the only application in the Adobe family that can open PDF files. Another often used app is Adobe Reader. Since both of the two applications are able for users to manage PDF files, some users might want to know what the difference between them is. Let's check the functions of these two applications.
Adobe Reader: Read PDF files and perform fundamental tasks like allowing users to fill in form fields and add some highlights.
Adobe Acrobat: Create PDF files from other formats, edit them in various ways, add form fields, security settings, etc.
