[EXT] Re: Unable to use XeTeX after updating to the 2023 version

[Volker RW Schaa]

The Windows file system supports setting case sensitivity with attribute flags per directory (since Windows 10, build 17107). While the standard behavior is to be case-insensitive, you can assign an attribute flag to make a directory case sensitive, so that it will recognize Linux files and folders that may differ only by case.
But whether you will be happy with this depends as always on the applications you use.
