Can I Recover PDF File?

It is indeed possible to retrieve PDF files. You can recover deleted PDF files, even without a backup. But certain conditions must be met:

  • New data haven't overwritten the space previously occupied by the deleted files.
  • The deleted PDF files were not stored on a solid-state disk (SSD) with TRIM enabled.
  • The storage device where the PDF files were kept is not physically damaged.

The first condition relates to how data is physically stored on storage devices. When you delete a PDF file on Windows or macOS, it doesn't immediately disappear. It is initially moved to the Recycle Bin or Trash folder, remaining there until it's permanently deleted. Even then, the file continues on the storage device and can be recovered until new data overwrites it.

However, there is an exception for situations where the lost data was on a TRIM-enabled SSD, the second condition. TRIM lets the operating system inform the SSD that specific data blocks are no longer needed and can be wiped out, making them writable again. If TRIM is enabled for your SSD, you likely won't be able to recover permanently deleted PDF files.

If the lost PDF files are on a physically damaged storage device that your computer can't recognize, the third condition applies. In such cases, a professional data recovery center might be able to assist, but the cost can be substantial.

In the following sections, we’ll introduce you to the best methods for recovering PDF files, whether unsaved or not.

How to Recover Deleted PDF Files?

Before we explore the steps for PDF recovery, let's first understand the potential reasons behind the problem. Losing your PDF files can occur due to various factors, such as:

  • Download or file transfer problems.
  • Unintentional file deletions.
  • Issues with hard drive or storage device integrity.
  • Accidental drive or partition formatting.
  • Malware or virus infections.
  • Logical or physical damage to storage devices.

No matter why you lost your data, 3 proven methods can assist you in recovering deleted PDF files.

Method 1. Retrieve PDF Files from the Recycle Bin

When you remove a file from your Windows PC, it usually ends up in the Recycle Bin – unless you use Shift+Delete. So, your first step should be to check the Recycle Bin for accidentally deleted PDF files.

Here's how to do it:

Step 1: Double-press the Recycle Bin icon to open it.

Step 2: Locate the deleted PDF file and select it.

Step 3: Click Restore in the pop-up menu that appears. This action will return your file to its original location, making it accessible through your applications.

Note: You can also cut and paste the file from the Recycle Bin to your preferred location or simply drag and drop the files out of the Recycle Bin.

Keep in mind that this method is effective for recently deleted files that are still in the Recycle Bin. If the Recycle Bin has been emptied or data has been removed due to expiration settings, you'll need to explore other recovery methods.

Method 2. Recover PDF Documents Using Wondershare Recoverit

But what if you've already emptied the Recycle Bin? In such a situation, the only solution is to use a capable PDF recovery tool to retrieve your deleted PDF files. Wondershare Recoverit is a highly effective tool for recovering data, including deleted and formatted PDF files.

Method 3. Restore PDF Files via Windows File History

File History is a useful feature in Windows that can recover previous versions of your files. It's a straightforward and built-in way to retrieve your lost PDF file. If you've misplaced an important PDF document, you can utilize the File History feature to access your file backups.

However, it's essential to confirm that File History is enabled for this method to be effective. To enable it, follow these steps:

Step 1: Access the Restore files using File History option through the Windows search tab, which will lead you to the Control Panel.

Step 2: In the Control Panel, activate File History.

Step 3: Once File History is enabled, go to the folder where you originally saved your PDF file. Search and click the file you wish to restore. Then, click the Restore button, which is highlighted in green, to recover it.

How To Recover Unsaved PDF Files

Losing unsaved work on a PDF document can be frustrating, but there are methods to help you recover it. Here are two effective techniques:

Method 1: Use Auto-Recovery Function in Adobe Acrobat Reader for Lost PDF Files Recovery

Adobe Acrobat Reader has a useful Auto-Recovery function designed to protect your data in case of an abrupt shutdown due to power outages or severe software issues. While this feature cannot resurrect a permanently deleted PDF file, it can restore all the modifications you made to the PDF but hadn't saved before the unexpected closure.

To retrieve unsaved changes using the Auto-Recovery function:

Step 1: Open Adobe Acrobat Reader.

Step 2: When prompted to recover the auto-save file, select Yes.

Step 3: Save the recovered file in a secure location.

Method 2: Use Temporary Files to Recover PDF Document

The AutoSave function in the Adobe PDF editor is designed to help you preserve your edited PDF files. However, it's important to note that the AutoSave folder is automatically removed once you close Acrobat. This means you can't rely on AutoSave to recover unsaved files.

Most PDF applications include a feature for creating temporary backup files. When editing a PDF on your computer, the application generates a temporary file to safeguard your unsaved work.

If your PDF is closed due to unexpected hardware issues, a sudden power loss, or an unforeseen application error, there's still a chance of recovery. You can attempt to restore it from a temporary file. Here, we'll use Adobe Reader as an example to demonstrate how to recover an unsaved PDF:

Step 1: Locate the file path of PDF temporary files

The following are the paths to Adobe PDF temporary files:

  • C:\Users\Tracy\AppData\Local\Adobe\Acrobat\DC
  • C:\Users\Tracy\AppData\Roaming\Adobe\Acrobat\DC
  • C:\Users\Tracy\AppData\Local\Temp

Step 2: Find and identify the temporary files of the unsaved PDF.

Note: The extensions of temporary files may not match those of the original PDF files; they may have different extensions.

Step 3: Copy the temporary files to a secure location and change their file extensions to “.pdf.”

Step 4: Open the PDF file using Adobe Reader.

Following these steps, you can once again access, view, and edit your PDF file.

If the method described here doesn't yield the desired results, or if Adobe Reader or other PDF editing applications continue to experience corruption, proceed to the next section. You'll learn how to independently repair corrupted PDF files.
