How to get disk space of windows machine with R?

Question

How can I get the total disk space / free disk space of my windows computer ?

If there is no R function, maybe there is a windows command that I could use within the R system function but I wasn't able to find that command.

Answer 1

Though I find it really difficult to believe that a Google search for windows cmd disk space came up empty for you, this should provide the information you need w/o the need for admin privileges:

disks <- system("wmic logicaldisk get size,freespace,caption", inter=TRUE)

disks <- read.fwf(textConnection(disks[1:(length(disks)-1)]), 
         widths=c(9, 13, 13), strip.white=TRUE, stringsAsFactors=FALSE)

colnames(disks) <- disks[1,]
disks <- disks[-1,]
rownames(disks) <- NULL

disks

##   Caption   FreeSpace        Size
## 1      A:                        
## 2      C: 52617023488 63898120192
## 3      D:                        

Just thought I'd also add that this answer comes from someone who is primarily an OS X/Linux user.
