Download an online folder with Windows 10 - r

Question

I wish to download an online folder using Windows 10 on my Dell laptop. In this example the folder I wish to download is named Targetfolder. I am trying to use the Command Window but also am wondering whether there is a simple solution in R. I have included an image at the bottom of this post showing the target folder. I should add that Targetfolder includes a file and multiple subfolders containing files. Not all files have the same extension. Also, please note this is a hypothetical site. I did not want to include the real site for privacy issues.
EDIT
Here is a real site that can serve as a functional, reproducible example. The folder rel2020 can take the place of the hypothetical Targetfolder:

None of the answers here seem to work with Targetfolder:

Below are my attempts based on answers posted at the link above and the result I obtained:
Attempt One
lftp -c 'mirror --parallel=300 https://www.examplengo.org/datadisk/examplefolder/userdirs/user3/Targetfolder/ ;exit'
Returned:
lftp is not recognized as an internal or external command, operable program or batch file.
Attempt Two
wget -r -np -nH --cut-dirs=3 -R index.html https://www.examplengo.org/datadisk/examplefolder/userdirs/user3/Targetfolder/
Returned:
wget is not recognized as an internal or external command, operable program or batch file.
Attempt Three

VisualWget returned Unsupported scheme next to the url.

Answer 1

Here is a way with packages httr and rvest.
First get the folders where the files are from the link.
Then loop through the folders with Map, getting the filenames and downloading them in a lapply loop.
If errors such as time out conditions occur, they will be trapped in tryCatch. The last code lines will tell if and where there were errors.
Note: I only downloaded from folders[1:2], in the Map below change this to folders.
suppressPackageStartupMessages({
library(httr)
library(rvest)
library(dplyr)
})
link <- "https://www2.census.gov/geo/docs/maps-data/data/rel2020/"
page <- read_html(link)
folders <- page %>%
html_elements("a") %>%
html_attr("href") %>%
.[8:14] %>%
paste0(link, .)
files_txt <- Map(\(x) {
x %>%
read_html() %>%
html_elements("a") %>%
html_attr("href") %>%
grep("\\.txt$", ., value = TRUE) %>%
paste0(x, .) %>%
lapply(\(y) {
tryCatch(
download.file(y, destfile = file.path("~/Temp", basename(y))),
error = function(e) e
)
})
}, folders[1:2])
err <- sapply(unlist(files_txt, recursive = FALSE), inherits, "error")
lapply(unlist(files_txt, recursive = FALSE)[err], simpleError)
