How to Reset Details and Preview Pane Width Size to Default in Windows 8 and 10

information   Information
The details pane shows you see the most common properties associated with the selected file. File properties provide more detailed info about a file, such as the author, the date you last changed the file, and any descriptive tags you might have added to the file.

The preview pane shows you see the contents of a file, such as image or text files, without having to open it with an app.

You can adjust the width of the details pane or preview pane in File Explorer by dragging its left border to the left or right for the width you want. The details pane and preview pane share the same width setting. This is also a global setting that gets applied to all explorer windows in only your user account.

This tutorial will show you how to reset the width of the details pane and preview pane in explorer back to default for your account in Windows 8 and Windows 10.
