PDF Recovery: How To Recover Deleted/Unsaved/Corrupted PDF

PDF, also known as “Portable Document Format,” is a document format that was developed by Adobe in the 1990s. This file format quickly became popular and was used by many enterprises and organizations. One of the most obvious advantages of the PDF format is that it can consistently present document content even when it’s used on different devices or operating systems.

But as much as it’s widely used, only a few people know how to recover PDF files that get deleted or unsaved. Hence, we’ve prepared this post to show you that PDF file recovery is not as complicated as it may seem.

Can I Recover PDF Documents?

Yes, PDF documents can be recovered, but you need to use the right methods for 100% success. You also need to take certain precautions for smooth recovery. Some of these precautions are:

📌 Preparations	💡 Purposes
Stop Using the Disk	This is to prevent new data from overwriting the space occupied by the deleted PDF file. If you accidentally overwrite the data, you will need more operations to recover the replaced files.
Avoid Disk Defragmentation	The defragmentation of the disk may cause files to be overwritten. That means, lost PDF files become difficult to retrieve.
Check for Malware	Protect your system and other files from potential harm.

Search Temporary Files to Restore PDFs Unsaved

The computer keeps temporary files of every operation. Temporary files can help recover PDF documents not saved due to hardware issues, power loss, unforeseen application errors, etc. However, recent modifications made to the PDFs might not be recovered. This is because the computer was unable to record recent changes due to the unexpected shutdown, so you will get an older version of your files.

Here’s how to recover PDF not saved through temporary files:

Step 1. On Windows, open File Explorer. On Mac, open Finder.

Step 2. Find temporary file location. Oftentimes, it is:

Windows: C:\Users[Your Username]\App Data\Local\Temp

Mac: /private/var/folders

Step 3. Check for files that end with .tmp, .temp. or .asd

Step 4. Review them for anyone who matches the name or content of your unsaved PDF. Select the ones that match.

Step 5. Copy them to the desktop and change their extension to .pdf to make them recognizable as PDF files.

Step 6. Open the files with a PDF viewer or PDF editing application. This will let you know if they contain the content you’re looking for and if they are arranged as you last did.

Step 7. If you’ve found the PDF files you need, save them. If the selected files don’t include your unsaved PDF, go back to the temporary files location to check again.
