file.info returning NA values in r

Question

I am trying to get size of files and other details from my directory however it is returning NA values for some files but it is returning details for other files. Below is the code i used. will there be any administrator settings for files to fetch these details??

library(tidyr)
library(dplyr)
wd <- "F:\\working\\others"
setwd(wd)
#get file list - your list of files would be different
fileList <- list.files()[1:240]
class(fileList)
#result
cbind(
  file.info(fileList)[,c("size"), drop=FALSE],
  x = as.character(file.mtime(fileList))) %>% 
  separate(x,
           into = c("DateModified","TimeModified"),
           sep=" ") %>% 
  add_rownames %>% 
  select(DateModified,
         TimeModified,
         Size=size,
         FileName=rowname)

Answer 1

try this: the trick is in the full.names = TRUE

ldir <-  normalizePath("<type here the path of directory>")
finf <- file.info(dir(path = ldir, full.names = TRUE), extra_cols = FALSE)
View(finf)
