Question details

The user needs to restore the default system behavior so that ZIP files open correctly in File Explorer for extraction, rather than triggering a Microsoft Word error.

How to Fix ZIP Files Opening in Word Instead of File Explorer
Product
Microsoft Word
Device & OS
Windows
Scenario
Downloading multiple email attachments at once from Gmail generates a ZIP file archive that the user wants to extract.
Observed behavior
Double-clicking the downloaded ZIP file unexpectedly launches Microsoft Word and displays an error message instead of opening the archive in Windows File Explorer.
Before you start

Ensure you know the exact folder location where your browser saves downloaded ZIP files, typically the default Windows Downloads folder, so you can easily locate the file to modify its settings.

Solution 1Recommended

Restore File Association via the Open With Menu

The fastest way to resolve this issue is to manually reassign File Explorer as the default application for ZIP archives using the right-click context menu.

Sometimes, file extensions can accidentally be reassigned to the wrong application during updates or by a single misclick. Reassigning the .zip extension back to File Explorer will immediately resolve the Word error.

1
Locate the ZIP File

Open Windows File Explorer and navigate to your Downloads folder to find the downloaded Gmail attachment ZIP file.

2
Access the Open With Menu

Right-click the ZIP file, hover your mouse over 'Open with', and then click on 'Choose another app' from the extended menu.

3
Select File Explorer

In the pop-up window, select 'File Explorer' from the list of available applications.

4
Set as Default

Check the box at the bottom that says 'Always use this app to open .zip files' and click 'OK'. You can now right-click the file and select 'Extract All' to access your attachments.

Verification: Once completed, the icon for your ZIP files should immediately change back to the standard yellow folder with a zipper.

Frequently Asked Questions

Why did Microsoft Word suddenly start opening my ZIP files?

This commonly occurs either due to a buggy Microsoft Office update that unintentionally rewrites system file associations, or if a user accidentally selects Word from the 'Open with' menu while the 'Always use this app' checkbox is ticked.

Will changing the default app back to File Explorer delete my extracted files?

No. Modifying file associations only tells Windows which software program it should use to view a specific file type. Your downloaded attachments and original archives will remain perfectly safe and unmodified.

What should I do if File Explorer is missing from the Open with menu?

If File Explorer isn't listed, scroll to the bottom of the 'Open with' window and click 'More apps' or 'Look for another app on this PC.' You can then manually browse to your C:\Windows folder and select the 'explorer.exe' application.
