Example:
path <- system.file(package="base") pathnames <- list.files(path, full.names=TRUE) isDir <- file.info(pathnames)$isdir dirs <- pathnames[isDir] files <- pathnames[!isDir]
If you don't get the 'isDir' line, think of it as infos <- file.info(pathnames) isDir <- infos$isdir

For windows, how can I list only the folders in some folder? I was thinking that dir() and file.info() with isdir==TRUE being something that might work.
These folders or directories are numerically named with no dot extension names or other characters. Typically, these are 3132, 3334, ...
Here is what I tried. The last line is where I need more work.
pData="C:/Myfiles/R/Data/" setwd (pData) x <- dir(pData, all.files=F) y <- file.info(x, x$isdir==T)
TIA
