FCOPY, if I recall, does not change in separate operating systems, whereas system commands (Dos copy and Linux/Unix cp, obviously do). In a Windows 10 test, FCOPY (or Dos copy, for that matter) did NOT preserve the datetime metadata and, in fact, the "Date created" value was less than the "Date modified". This can be problematic in certain environments. Renaming using Dos rename did preserve the datetime metadata, so that suggests that zipping the file then moving the zip file then extracting could work, but a test showed that "Date created" then became "Date modified", which in this case was older. Note that the ZIP engine to the FILENAME also did not preserve these metadata; we discussed in the comments about using a System command and a third party compression program: https://blogs.sas.com/content/sasdummy/2015/05/11/using-filename-zip-to-unzip-and-read-data-files-in-sas/
