# Create fake archive directory with single tarball:

tarball <- basename (f)
archive_path <- file.path (tempdir (), "archive")
if (!dir.exists (archive_path)) {

path <- file.path (archive_path, tarball)
file.copy (f, path)

dir.create (tarball_path, recursive = TRUE)
file.copy (path, file.path (tarball_path, tarball))
