Remarks

On Windows, GetLogicalDrives returns the names of all accessible drives on a particular machine, including any optical drives or removable media devices, in the form "<drive letter>:\" (for example, "C:\"). On Unix, it returns the paths of all filesystem mount points mounted on a particular machine (for example, "/home/user", "/media/usb").
