fs.move fails with EEXIST even when overwrite option is enabled

It doesn’t happen all the time but sometimes I’m getting the following error message when using move() with the overwrite options:

{ Error: EEXIST: file already exists, link '/tests/fuzzing/sync/.sync/214b820bf10c4744994fb9a876e433d3.md_1498950555952' -> '/tests/fuzzing/sync/214b820bf10c4744994fb9a876e433d3.md'
    at Error (native)
  errno: -17,
  code: 'EEXIST',
  syscall: 'link',
  path: '/tests/fuzzing/sync/.sync/214b820bf10c4744994fb9a876e433d3.md_1498950555952',
  dest: '/tests/fuzzing/sync/214b820bf10c4744994fb9a876e433d3.md' }

I’m calling it like this, as a promise: fs.move(oldPath, newPath, { overwrite: true }); and most of the time it works but sometime it’s going to generate the EEXIST error. Any idea what could be the reason?

Hi, I have the same problem with my Windows 10 VM (which is not WSL if I understand well, if not, please tell me)

I think that this issue can occur while perform multiple move operation like this:

Promise.all([
    './foo/bar1',
    './foo/bar2',
    ....
    './foo/bar999'
].map((dest) => fs.move('./mySrc', dest, {override: true})));

Each of move operation include mkdirp itself and can fail on creation common root folder in concurrency mode.
