R help - Mar 2018 - Limit in Directory Hierarchy?

A quick question - is there a limit to the number of levels one can go down when
setting the directory in R studio?
I ask because I have been trying to set the directory to a folder 8 levels down
which R studio won't allow, and when I try to set the directory through
Session/Set Working Directory, it won't even show the lowest level folder:

setwd("C:/Users/supermollusc/Desktop/151017 Shellfish/Mussel Months/Mussel
Mar 18/0318.data")

but it's quite happy to set the directory at 7 levels

setwd("C:/Users/supermollusc/Desktop/151017 Shellfish/Mussel Months/Mussel
Mar 18")

I can't see why it won't do this if there isn't a hierarchy level
limit but I can't find reference to one on the net

Thanks

This is the wrong place to ask what RStudio can or cannot do. However, if your
question is about R you should try invoking your reproducible example in RGui or
the command line R.exe before posting here.

R has no directory depth limit. There is an operating system limit on returning
paths more than 260 characters long, and this seems to create problems sometimes
(Google it). You might also look at operating system permissions for the
"0318.data" directory.
