Windows 10: How to set certain types of files to read-only by default?

Context: I use a windows 11 computer to process data recorded by a scientific instrument. The data usually comes in the format of csv files.Question: Is there a way to set, for example, all .csv files to read-only by default, unless otherwise modified in file property menu? This is to prevent accidental writes.

How to change default app to open certain file types.

It's not as simple as it seems
Although it's easy as pie to change default apps by type file, but how to do it if I want to use app that's not on the default Window list?
Like in this example,



File is opened by IE but I have installed in my system programme called Notepad++ and I want it to open .xml files whenever i double click on them. But Notepad++ is not on the Windows list



So how to set this up to open .xml files with Notepad++?

 

How to set default app for file type jpg

I would like to change the default app for the file type jpg. I've gone through all the steps for setting a default app but the jpg file extension does not appear in the list and therefore I cannot choose a default.

When I Open a jpg file it opens in the Photo app. If I look at the Photo app's settings of default file types, jpg is not there.

Ditto for file type png.

How can I access the default setting for these and other "hidden" types?

 

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.
