Create a Copies of Files

Description

I often want a timestamped copies as backup of files or directories.

Usage

file_save(
  ...,
  file_extension_pattern = "\\.[A-z]{1,5}$",
  force = TRUE,
  recursive = NA,
  stop_on_error = TRUE,
  overwrite = FALSE
)

Arguments

...	Paths to files.
file_extension_pattern	A Pattern to mark a file extension. If matched, the time stamp will get inserted before that pattern.
force	Force even if file_extension_pattern is not matched. Set to FALSE to skip stamping such files.
recursive	Passed to file.copy. Defaults to 'if the current path is a directory, then TRUE, else FALSE'.
stop_on_error	Throw an exception on error?
overwrite	Passed to file.copy.
