File Explorer Doesn't Show Preview for Word, Excel, PPTX, and TXT Files

File Explorer is a powerful tool in Windows that allows you to browse and manage your files and folders. However, sometimes you may encounter an issue where File Explorer doesn't show a preview for Word, Excel, PPTX, and TXT files. This can be frustrating, especially when you need to quickly preview the contents of these files. In this article, we will discuss some possible reasons for this issue and provide solutions to fix it.

Reasons for File Explorer not showing preview for Word, Excel, PPTX, and TXT files

There can be several reasons behind File Explorer not showing a preview for Word, Excel, PPTX, and TXT files. Let's explore some of the common causes:

1. File associations: File associations determine which program should be used to open a particular file type. If the file associations for Word, Excel, PPTX, and TXT files are incorrect or missing, File Explorer may not be able to generate a preview.
2. Thumbnail cache: File Explorer uses a thumbnail cache to store previews of files. If the thumbnail cache is corrupted or outdated, it can prevent File Explorer from showing previews.
3. Third-party software: Sometimes, third-party software or extensions can interfere with File Explorer's ability to generate previews. These software or extensions may modify the default behavior of File Explorer and cause the preview feature to stop working.

Fixes for File Explorer not showing preview for Word, Excel, PPTX, and TXT files

Now that we understand the possible reasons behind the issue, let's discuss some solutions to fix it:

Method 1: Check file associations

The first step is to ensure that the correct program is associated with Word, Excel, PPTX, and TXT files. Here's how you can check and set file associations:

1. Open the Control Panel by searching for it in the Start menu.

After setting the correct file associations, check if File Explorer can now show previews for Word, Excel, PPTX, and TXT files.

After clearing the thumbnail cache, check if File Explorer is now able to show previews for Word, Excel, PPTX, and TXT files.

Method 3: Disable third-party software or extensions

If you have recently installed any third-party software or extensions related to file management or preview, they may be causing conflicts with File Explorer. To check if this is the case, try disabling or uninstalling these software or extensions. Here's how:

1. Open Task Manager by right-clicking on the taskbar and selecting Task Manager.
2. Click on the Startup tab.
