Use
basename("C:/some_dir/a.ext")# [1] "a.ext"dirname("C:/some_dir/a.ext")# [1] "C:/some_dir"
The tidyverse equivalent lives in the fs package. {fs} makes use of libuv under the hood.
library("fs")path_file("/some/path/to/file.xyz")#> [1] "file.xyz"path_dir("/some/path/to/file.xyz")#> [1] "/some/path/to"
