Copy folder recursive in R

Question

Am I missing something in the functions?
I want to copy a folder with some files and another subfolder from one location to another. I tried to use file.copy(from, to,

Answer 1

If you want to copy files that lie inside one folder so that they lie inside of a second folder e.g.

dir1/file1.txt
dir1/nested/file2.txt

to:

dir2/file1.txt
dir2/nested/file2.txt

Then this code works:

from <- "dir1"
to   <- "dir2"
file.copy(list.files(from, full.names = TRUE), 
          to, 
          recursive = TRUE)

Avoid using recursive=TRUE in the list.files() command otherwise you lose the nesting.

file.copy(list.files(from, full.names = TRUE, recursive = TRUE), 
          to, 
          recursive = TRUE)

# incorrect
# dir2/file1.txt
# dir2/file2.txt

Other answers above didn't help with above scenario, eg:

file.copy(from, to, recursive=TRUE)

# incorrect - makes:
# dir2/dir1/file1.txt
# dir2/dir1/nested/file2.txt

file.copy('(...)/path_to_folder_Z', '(...)/folder_X')
# overwrites existing folder if in same parent directory
