Q.>> Here i have a file path, for eg : - FPath <- "D:\\MyFolder\\MyFile.txt" >> HOW IS POSSIBLE TO GET THE FILE NAME FROM THIS GIVEN PATH ?A.> x <- substr(FPath,13,nchar(FPath)) should give you the desired output.But this is much like saying x <- "MyFile.txt" will give you the desired output - where did the 13 come from? Use basename() for a general solution. > basename(FPath) [1] "MyFile.txt" dirname(FPath) gives you the directory that FPath is in in. (To other responders, those who don't know that all caps means shouting probably don't know that the answer '?basename' means to type that into R to look at the help file for the basename function.)

Yes, basename(filepath) assumes that filepath represents
path to a file on the OS that R is running on. Hence, on
Windows we get
> basename("dir\\path")
[1] "path"
> basename("dir/path")
[1] "path"
because both / and \ are valid separators (and invalid in file names)
Linux allows \ in a file name so we get
> basename("dir\\file")
[1] "dir\\file"
> basename("dir/file")
[1] "file"
The same goes for dirname():
Windows> dirname("c:/file") # "c:" is not a directory
but "c:/" is
[1] "c:/"
Linux> dirname("c:/file")
[1] "c:"

If this is an answer, and we really appreciate people who try to help, please a) cite the question and b) provide answers that at least work for you. Yours has way too many errors or typos.
