PDF (Portable Document Format) files are widely used for everything from personal eBooks to legal contracts and business reports. Their compatibility across different platforms and their preservation of formatting make them a preferred choice for document sharing.
1. Check the Recycle Bin or Trash
Before diving into advanced solutions, always start with the basics. If you've recently deleted a PDF file, it's often still recoverable from the Recycle Bin (Windows) or Trash (Mac).
Windows
Double-click the Recycle Bin icon on your desktop.
Look for your deleted PDF file by name or date.
Right-click the file and select "Restore" to return it to its original location.
Mac
Open the Trash from the dock.
Browse or search for the missing PDF.
Right-click and select "Put Back" to restore it.
2. Use File History or Time Machine
If you’ve enabled backup features on your operating system, retrieving deleted or previous versions of PDF files can be very straightforward.
Windows File History
Go to the folder where the PDF file was stored.
Right-click inside the folder and choose "Restore previous versions."
Choose the version containing your PDF and click "Restore."
macOS Time Machine
Connect your Time Machine backup drive.
Open the folder where the PDF was saved.
Launch Time Machine from the menu bar.
Use the timeline to locate and restore the PDF file.

Click the Start menu and type *.pdf to search for all PDF files.
Narrow the search using filters like date modified, size, or location.
macOS Spotlight Search
Press Cmd + Space to open Spotlight.
Type kind:pdf followed by keywords related to your file.
