FileTypeDiag Dumps Complete File Type Association Info for Troubleshooting

Caracara.my.id - FileExtInfo is a small tool I created several years back, and haven’t had the chance to update it for the latest versions of Windows. Although it just runs fine even in Windows 10 but doesn’t enumerate entries in the 32-bit node in Windows 64-bit systems.

There is another useful tool for dumping file association information to a file; check out FileTypeDiag from pretentiousname.com, the same site which released a popular fix for the Adobe PDF thumbnails issue.

FileTypeDiag Utility

filetypediag FileTypeDiag generates complete file association information for the file extension you specify. File type associations can be a complicated thing for many, but this tool makes everything easy by listing out all the file class data and also the Default Programs registration details for troubleshooting.

This tool can be helpful to troubleshoot cases such as:

 1. Files don’t open when double-clicked, or open in the wrong application.

 2. An incorrect icon is shown for a file type, although the file association is correct.

 3. Clicking a media file causes explorer to crash. You need to investigate shell extensions for that file type.

 4. Thumbnails or video previews (preview pane) are not generated.

 5. An unwanted entry appears in the right-click menu for a particular file type that you want to remove.

 6. Programs missing from Default Programs or Default Apps

and for fixing other obscure problems.

In the FileTypeDiag window, type the file extension which you want to investigate and click Save. The output is saved to a text file.

If you’re not sure what exactly to look in the text file, zip the file and send it to someone who can interpret the entries. If you want me take a look at the report (for free), get in touch with me via the contact form on this site. I would be glad to help.
