Windows 10 now handles case sensitive files, just like Linux, and here are the steps to enable the features.
Although you can now run a number of Linux distros natively on Windows 10, this integration has been a little tricky when it comes to handling filename case, as Linux is case sensitive and Windows is not.
In order to overcome this limitation, starting with the Windows 10 April 2018 Update (version 1803), NTFS includes a new flag that you can enable on a per-folder basis allowing the file system to treat files and folders as case sensitive.
Using this new flag, you can not only handle case sensitive files while using a Linux console but more importantly, it also allows Windows applications (such as Word and Notepad) to open files correctly if they're only different by case.
