is there a difference between .rmd and .Rmd files?

I wanted to know if there's a difference between .Rmd files and .rmd files (uppercase vs lowercase). When I test it, there doesn't seem to be one.

As commented above earlier, the short answer is 'no -- there is no difference'.

The larger context is that for some operating systems, file.rmd and file.Rmd are in fact the same as they are on purpose treating filenames in a case-insensitive matter. (In hindsight that quite likely might not have been their brightest idea---but stuff happens and now it is a fact that is hard to undo.) So R plays along and treats them the same way too.

You can even dig around existing R packages (and browsing e.g. at https://github.com/cran/ lets you view all CRAN packages via that 'mirror') and may notice that some packages do in fact use file.r even if most stick with file.R. Again, they are treated the same by R, reflecting the fact that one of the operating systems R runs effectively enforces that.
