Yes. You are right that is the trick:)

Not sure why, file.info is not working for the array of input files/folders/etc. but successfully works when an individual file in input.
Look at what list.files() returns: there is no path, just the filename.
If you want to use file.info, you need the full path, so you'd use
file.info(list.files(input_path,full=TRUE))
(That takes a long time, by the way: there are a lot of files there,
and they all need to be opened for inspection!)

Thanks again for your insights and feedback.

Yes. You've overlooked the trick of telling us about
the specifics of
your operating system, version of R, etc., and of showing
exactly what
commands you ``tried'', i.e. of reading the Posting Guide.
