【BUG REPORT】windows copy file to root directory error

[maxhub-fe]

const cpfile = require('cp-file');
const path = require('path')

const src = path.resolve(__dirname, './index.js');
const dest = "D:\\"
cpfile(src, dest, {
 }).on('progress', (process) => console.log(process)).then(done => console.log({done}))
 .catch(e => console.log(e));

stack:

$ node index.js
{ NestedError: Cannot create directory D:\: EPERM: operation not permitted, mkdir 'D:'
at makeDir.catch.error (d:\code\tset\node_modules\cp-file\fs.js:82:8)
Caused By: Error: EPERM: operation not permitted, mkdir 'D:'
nested:
{ Error: EPERM: operation not permitted, mkdir 'D:' errno: -4048, code: 'EPERM', syscall: 'mkdir', path: 'D:\' },
errno: -4048,
code: 'EPERM',
syscall: 'mkdir',
path: 'D:\',
name: 'CpFileError' }

I found that it was 'make-dir' cause error
mkdir

On Windows, using fs.mkdir() on the root directory even with recursion will result in an error:

fs.mkdir('/', { recursive: true }, (err) => {
  // => [Error: EPERM: operation not permitted, mkdir 'C:\']
});

@sindresorhus help plz !!!

I was having the same issue, fixed it by forking, adding a check and using it from my repo.

if(process.platform==="win32" && path.length===3 && path[1]===':') console.log("skipping root directory")

Yeah, I know, it is ugly but it works

It would be better if we replace
https://github.com/sindresorhus/cp-file/blob/589c637db381f93479031afaa8ab6ba907b7a957/index.js#L15

with

if(!(process.platform === "win32" && /\w:\\/.test(path.resolve(path.dirname(destination), "/")))){
        await fs.makeDir(path.dirname(destination), {mode: options.directoryMode});
}
