Is there a built-in function to get the size of a folder?

General Usage
1

I saw that there are stat and filesize, but I don’t see a recursive option.

Is there a small package or another function that can give me the cumulative size of all files in a folder?

Another thing I am not sure about is if stat works on windows?

I tried the code below and I think it works now.

using Logging
function totalsize(dirpath)
	total = 0
	for (root,dir,files) in walkdir(dirpath)
		total += filesize(root)
		@info filesize(root) root
		for f in files
			file = joinpath(root,f)
			size = filesize(file)
			total += size
			@info size file
		end
		print(" "^80,"\r")
		print(total," B","\r")
	end
end

Yeah that was a stupid mistake. Thanks

Here is a version that is less noisy.
Is it bad practice to add methods to Base?

function Base.filesize(dirpath::String, recursive::Bool)
	if !recursive
		return filesize(dirpath)
	else
		total = 0
		for (root,dirs,files) in walkdir(dirpath)
			total += filesize(root)
			for f in files
				file = joinpath(root,f)
				size = filesize(file)
				total += size
			end
		end
		return total
	end
end

Example:

julia> map((x)->basename(x)=>filesize(x,true),
           readdir(joinpath(homedir(), ".julia"), join=true))
14-element Vector{Pair{String, Int64}}:
       "artifacts" => 2647756716
          "clones" => 4096
        "compiled" => 641285002

But what if there are many levels of folders in each folder?

In this case, this method definition is a type piracy.
According to official documentation:

“Type piracy” refers to the practice of extending or redefining methods in Base or other packages on types that you have not defined.

And yes, type piracy is considered bad practice.

The code should work in that case.
walkdir walks through the full substructure of the folder.
