Root Director already exists on Windows

[dsbert]

The following is failing on Windows.

    mockfs.restore();
    mockfs(
      {
        "C:\\": {
          "temp.DAT": "original file contents",
          "upload.DAT": "new file contents"
        }
      },
      { createCwd: false }
    );

Results in this error

Item with the same name already exists: \\?\c:

      at Directory.Object.<anonymous>.Directory.addItem (node_modules/mock-fs/lib/directory.js:37:11)
      at populate (node_modules/mock-fs/lib/filesystem.js:160:15)
      at Function.Object.<anonymous>.FileSystem.create (node_modules/mock-fs/lib/filesystem.js:192:5)
      at mock (node_modules/mock-fs/lib/index.js:59:27)
      at Object.test.only (src/handlers/uploadHandler.test.js:131:5)
          at new Promise (<anonymous>)

Also, if I try changing it to this

    const tempPath = `C:\\temp.DAT`;
    const uploadPath = `C:\\upload.DAT`;

    mockfs.restore();
    mockfs({
      [tempPath]: "original file contents",
      [uploadPath]: "new file contents"
    });

    const copyFileAsync = util.promisify(fs.copyFile);
    await copyFileAsync(tempPath, uploadPath);

I end up with the following error;

[Error: ENOENT: no such file or directory, copyfile 'C:\temp.DAT' -> 'C:\upload.DAT']

I'm having the same issue. A bit confused (probably my lack of understanding something).

Ok, the issue was it didn't like the fake path I was using. This works. Before I was using process.cwd() to the path names was colliding.

beforeEach(() => {
  mock({
  'path/to/dir': {
    '07-20-18.txt': 'lets try this',
    }
  });
})
