My preview pane works for all typical files, .txt, .pdf, .jpg etc...


I use a program, and it saves files with the extension .blt

Those files can also be opened in notepad, and are 100% text based.


In every PC since windows 7 I have always managed to use PreviewConfig.exe to set the extension viewable in the preview pane.

I have had two previous PC's runningWindows 10, and set up at least 5 others and have been able to see the file contents without much trouble.

Now, I have a new laptop, windows10 pro, and the steps I have always followed in the past are not working.


Looking into it further I checked the registry, and here is what I have...


(Default) = MYPROG
PerceivedType = text
Content Type = text/plain


and in...




the default handler for text files looks good too...


I have gone trough


at least 10 times...


I tried setting notepad as the default for .blt, and no good...


No matter what I try, I simply can not see my files contents in the window preview pane.


Any suggestions from the IT Gods ?
