Fix Windows 10 File Explorer Crashing When Moving PDF Files
Question details
The user experiences sudden crashes in Windows 10 File Explorer when attempting to move PDF files between folders.

- Product
- Windows File Explorer / Adobe Acrobat Pro DC
- Device & OS
- Windows 10
- Scenario
- Moving PDF files from one directory to another.
- Observed behavior
- File Explorer unexpectedly closes or crashes during the PDF file transfer process.
Ensure all active PDF documents are fully closed, and verify that you are using Windows File Explorer rather than a web browser like Microsoft Edge to manage your files.
Set Default PDF Viewer and Close Active Files
File Explorer may crash if Edge is trying to preview PDFs or if files are currently open in the background. Changing the default application can prevent these conflicts.
In Windows 10, Microsoft Edge or unstable preview handlers might be associated with PDF viewing by default, which can cause File Explorer to freeze or crash when moving files.
Ensure that the PDF files you are trying to move are not currently open in Adobe Acrobat, Microsoft Edge, or any other PDF reader.
Right-click any PDF file on your computer and select 'Properties' from the context menu.
In the General tab, look for the 'Opens with' section and click the 'Change' button.
Select 'Adobe Acrobat' (or your preferred dedicated PDF application) from the list and click 'OK'.
Click 'Apply' and 'OK' in the Properties window, then attempt to move your PDF files again.

Update Windows 10 and Adobe Acrobat Pro DC
Outdated software or operating system bugs can cause compatibility issues leading to File Explorer crashes.
Manage and Edit PDFs Seamlessly with WPS Office
Avoid system crashes caused by heavy PDF software conflicts. WPS Office includes a lightweight, built-in PDF editor that allows you to view, edit, and organize PDF files safely without overloading Windows File Explorer.

- 4. Manage PDFs securely: Organize, compress, or export your PDFs directly within the application without relying on unstable Windows preview handlers.

Frequently Asked Questions
Why does Windows 10 File Explorer crash only when moving PDF files?
This usually occurs due to a conflict with PDF preview handlers in File Explorer, or because the PDF file is still being processed in the background by software like Adobe Acrobat or Microsoft Edge.
Can disabling the Preview Pane in File Explorer stop the crashes?
Yes. Open File Explorer, go to the 'View' tab at the top, and ensure 'Preview pane' is unchecked. This stops Windows from attempting to render the PDF visually while you are moving it, which frequently prevents crashes.
Does clearing the File Explorer history help with PDF crashes?
It can help. Open File Explorer, click the 'View' tab, select 'Options', and under the General tab, click 'Clear' next to 'Clear File Explorer history'. This removes corrupted cache data that might be causing instability.
