However the reason for my 2nd post was that I could *not* at all confirm what Mario reported, but rather I saw having a final "/" and not having it to give the *same* behavior on R for Windows versions from 3.6.1 to 4.1.2 on our M$ Windows terminal server (2016) and now, as I just checked, it also *still* has the same Windows-specific behavior in R-devel-ucrt (the one from Tomas Kalibera) : If I use a trailing `/` or `\\` it is *kept*, but no additional fsep (i.e. '/' or `\\`) is added (on Windows) when I use list.files(dir, full.names=TRUE) contrary to what Mario reported (to happen in R 4.1.2, but not R 3.6.1) Martin ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
