Why did you jack up Preview in File Explorer?

Question

I really hate that you took the ability to scroll, enlarge previews in my file explore. YOU'RE NOT THINKING OF THE END USER. This has caused me a lot of extra work & hardship. I work with thousands of documents per day & need to be able to read them in preview so I can sort them correctly. Please return “Preview” to the original format so I can work more seamlessly.

Hi Kathy Matt,

Welcome to the Microsoft Q&A forum.

I understand how important the Preview feature is when you’re working with a large volume of documents, and I appreciate you explaining how this change affects your daily workflow.

In recent versions of Windows 10, File Explorer’s Preview pane behavior has been updated. While the Preview pane is still available, some earlier interactions (such as zooming and smooth scrolling within the preview) are no longer supported in the same way. These updates focus on consistency and performance across file types.

That said, here are some practical ways that you can try to work more efficiently when reviewing and sorting documents:

1, Use the Details pane

• Open File Explorer > View > Details pane
• Select a file to quickly review metadata and key information without opening it.

2, Open files with a lightweight viewer

• Set Microsoft Edge as the default for PDFs to enable fast zooming and scrolling.
• Open a file, review it quickly, then close and move to the next one.

3, Ensure preview handlers are enabled

• File Explorer > View > Options > View
• Enable Show preview handlers in preview pane
• Disable Always show icons, never thumbnails

As an alternative workaround, you may consider using third‑party viewers or document management tools for high‑volume document review to provide richer preview controls.

File Explorer’s Preview pane behavior and capabilities are controlled by Windows features and, in some cases, by add-ons such as PowerToys. The core Preview pane in Windows 10 has not been restored to an older, more feature-rich design; instead, recent changes and security hardening can make previewing and working with many files feel more limited.

For scenarios that involve working through large numbers of documents, there are two main angles to check and improve the experience:

1. Verify that Preview handlers are actually enabled
   In some configurations, the Preview pane appears but does not show content as expected. Ensure that Windows is allowed to use preview handlers:
   1. Open File Explorer.
   2. Select View > Preview pane to show the pane.
   3. Select View > Options > Change folder and search options.
   4. On the View tab, under Advanced settings, make sure Show preview handlers in preview pane is selected.
2. Extend Preview capabilities with PowerToys File Explorer add-ons
   PowerToys adds enhanced preview support for many file types and can make the Preview pane more useful when sorting and reviewing documents:
   1. Install PowerToys (see Microsoft PowerToys).
   2. Open PowerToys and go to File Explorer add-ons.
   3. Turn On the preview extensions needed for the document types in use (for example, PDF, Markdown, source code files, etc.).
   4. If previews still do not appear, confirm again in File Explorer Options that Show preview handlers in preview pane is enabled.
   PowerToys previewers support:
   • PDF files (.pdf)
   • Markdown files (.md)
   • Source code files (.cs, .cpp, .rs, and many more)
   • SVG images (.svg)
   • G-code and QOI images
   PowerToys also provides thumbnail previews (for example, for PDF and SVG) so that files are easier to visually identify when browsing large folders.
3. Be aware of security-related preview restrictions
   For files downloaded from the internet or opened from certain network locations, newer Windows security updates can disable preview by default to protect against credential-leak vulnerabilities. In those cases, File Explorer may show a warning instead of the preview. If a file is trusted and must be previewed frequently:
   • Right-click the file, select Properties, and select Unblock (if available). The change may take effect after the next sign-in.
   • For trusted network locations, an administrator can move the share into a safer security zone using Internet Options > Security (note that this relaxes security for all files from that share).
4. OneDrive and thumbnails (if working from synced folders)
   When working with thousands of documents stored in OneDrive, thumbnails and previews may be controlled by OneDrive behavior:
   • Ensure the OneDrive folder view is set to medium icons or larger.
   • If thumbnails do not appear, use Always keep on this device on the files or folders that must be browsed visually.
   • Note that OneDrive does not provide previews/thumbnails for PDFs or images larger than 100 MB.

These steps do not revert File Explorer to an older design, but they restore and extend preview functionality as much as current Windows and security constraints allow, which can reduce the extra work when sorting and reviewing large numbers of documents.
