file_delete()1. Delete an observation file (“summary_obs.xlsx”) from a folder (“obs_2022-03-15”).
Let’s review the current files in both folders.
Files in “obs_2022-03-15”
base::basename(fs::dir_ls(here::here("file-system", "obs_2022-03-15")))[1] "obs1.xlsx" "obs2.xlsx" "obs3.xlsx" "summary_obs.xlsx"Now let’s delete “summary_obs.xlsx”
fs::file_delete(path = here::here("file-system", "obs_2022-03-15", "summary_obs.xlsx"))Now let’s view our files in the folder.
base::basename(fs::dir_ls(here::here("file-system", "obs_2022-03-15")))[1] "obs1.xlsx" "obs2.xlsx" "obs3.xlsx"2. Delete ALL files from a folder (“obs_2022-03-15”).
If we wanted to delete ALL files in the folder “obs_2022-03-15”, we could grab all our file names and pass that in our path.
files <- base::basename(fs::dir_ls(here::here("file-system", "obs_2022-03-15")))
fs::file_delete(path = here::here("file-system", "obs_2022-03-15", files))Now let’s view our files in the folder.
They are all gone.
base::basename(fs::dir_ls(here::here("file-system", "obs_2022-03-15")))character(0)Another option is to delete the entire folder by simply not listing any specific files.
fs::file_delete(path = here::here("file-system", "obs_2022-03-15"))Return to File System
