About PDF files

PDF file

PDF (Portable Document Format) files are designed by Adobe for the convenient use of large documents. The PDF file fully preserves the original image of the page with its font, color, size, etc., which in turn prevents any kind of plagiarism. This format is often used for printing out documents, for reading electronic books and important files, etc. But we must not forget that, like any other document, a PDF file may be lost for various reasons. And if you are not backing up, this can be a huge problem for you.

So, how do you recover PDF files in this case?

Method 1. Update your PDF reader

The most common reader for PDF files is Adobe Acrobat, but whatever PDF reader you use, update the software. To get started, go to the application and on the taskbar select the Help tab. Now go to “Check for updates”. You will see one of the following messages:

  • “Program updated.” If so, this way of recovering files does not suit you.
  • “There are updates to install.” You need to install the latest updates, then restart the computer and check if the PDF files are restored. If this method did not help, proceed to the next method.

Method 2. Try another reader for PDF files

Try opening the PDF file with other software or on another device. For example, if you can open a PDF file on your phone or tablet and cannot do it on your computer, then there is a problem in the PDF reader software. So try downloading another application and open the PDF file with it.

Did this not help? Read on.

Method 3. Find temporary files if you need to perform PDF Recovery

So what should you do first to repair a damaged PDF file? All temporary files are stored in specific folders, which are securely hidden from accidental deletion and unnecessary eyes. Therefore, by knowing their location, you can get to them and restore the necessary data.

There are several temporary file locations:




Here you can find your files, but remember that their quality may differ from the original. This should not confuse you. After all, renaming a file format is quite simple.

Method 4. Recover a previous version of the PDF file

Windows 10 has a recovery utility that is built-in. Using it, you can try PDF recovery. You need to go to Explorer and select your PDF file with the right mouse button. Now select “Restore previous versions”. A new window will display a list of all old versions of the file. Select the file you need and click Restore. If this method also did not help, proceed to the next.
