Why did you try to open them in Word?  What are you trying to do with them?  They are only text files, so if you have a decent text editor (Notepad++, EditPad etc.) you can open them and view the contents.  May not be very helpful for you though.  This is the default template from my machine for example:

In fact,  Ididn't mean to do it. I was just "tidying" my folders.

Now they are "attached" to Word and Studio can't open them. So I was wondering how to "restore" them.

So you get an error message on starting Studio or only when you try to open them in the project template editor?

Either way you could try this:

1. rename this folder - c:\Users\[USERNAME]\Documents\Studio 2021\Project Templates\
   Call it c:\Users\[USERNAME]\Documents\Studio 2021\Project Templates_old\ for example
   
   
2. restart Studio

Thank you for your answer

Did it solve your problem

I have changed the name as you mentioned.

Word is still there.

When I try to open them with Studio, I get a message saying (I translate): "this kind of file is not supported". 

But after all, may be it doesn't matter or perhaps they aren't intended to be open by Studio?

Thank you anyway.

I don’t understand why you are trying to open them for translation with Studio?
