Multiple iterations of dirEntries can produce different
results, which may or may not be what your program will be
happy with.
Sticking an .array at the end will iterate a single time and
maintain the list forever because .array returns an array. :)
auto entries = dirEntries(/* ... */).array;
I'd be cautious of that. I don't know what the underlying code
uses, it may reuse buffers for e.g. filenames to avoid
allocation.
If you are confident the directory contents won't change in
that split-second, then I think iterating twice is fine.

Steve,
The Rmd files are not on a network drive, but saved locally.
So, I'm confident, the files won't change in a split-second.
