Folders are not created on Windows

[codingcodax]

Describe the bug:

In Windows folders(predefinedFolders and additionalFolders) are not created as in Linux, while in Linux they are created.

Expected behavior (next.js) :
Create predefinedFolders and additionalFolders like assets, lib, utils, etc.

reexjs-app/
├── package.json
├── package-lock.json
├── pages/
├── public/
├── README.md
├── styles/
├── predefinedFolders/
└── additionalFolders/

This is the same with react.js.

node version : 14.16.1
npm version : 7.11.1
reexjs-cli : 0.1.7
