Lua os.remove() folder results in 'Permission denied'

Question

I am trying to use os.remove() to delete an empty folder in Windows using Lua but it just results in 'Permission Denied'. I can delete files with no problem.

However if I use os.execute() to call rmdir the folder does get deleted.

What are the limitations with os.remove() in a Windows environment?

Answer 1

The os.remove documentation states:

Deletes the file (or empty directory, on POSIX systems) with the given name. If this function fails, it returns nil, plus a string describing the error and the error code.

Windows is not POSIX compliant OS, therefore; exhibiting such a behaviour.

To get POSIX compatibility in Windows 7, you have to activate the Subsystem for UNIX-based applications (SUA / Interix) in Windows.
