Common PDF lost situations

I was working on a PDF file for hours on my MacBook. I remembered to save it and then minimized it after editing. My laptop battery died. When I charged and opened it but the PDF file is gone. Is there any way to recover it? Thx in advance.

I deleted a PDF file on My Mac, and then I emptied the Trash. I thought I would never need it. But the very next day, I regretted. And I couldn’t find it anywhere on my Mac. It was gone! How stupid I am! Is it possible to recover the deleted PDF file?

Actually, PDF files can be lost due to many reasons including unintentionally deleting, emptying the Trash, formatting hard drive, partition loss, corrupted operating system, infection of virus, etc. But it is possible to recover Mac deleted or lost PDF files.

When you delete a PDF file on your Mac, your Mac does not actually erase the actual data of the file. Instead, it just quickly changes the corresponding record in the file system to mark the PDF file as “deleted”. And the space of your deleted PDF file is available for use. When the system needs space to write another file, it may claim that space and store a different file in it. This is the point at which the actual data is lost.

So before your deleted or lost PDF files are overwritten by new files, they can be recovered. That’s why you should stop using your Mac when you find you PDF file missing or deleted by mistake. To recover a lost or deleted PDF file, you need a PDF file recovery tool to get them back. But there are some situations you can’t recover the PDF files by using any PDF recovery tool.

  • Your lost or deleted PDF files are overwritten by new files.
  • Your PDF files are never saved on your Mac. If you are working with a PDF file, and you even don’t save it on your Mac for one time, then you can’t recover it because it never exists on your Mac.
  • Your PDF files are heavily damaged or corrupted.
