You don't have to do anything if you're on Windows 10 ver 1607 or later, have `HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled` DWORD=1, and your application manifest declares itself `longPathAware`.

Or for older Windows versions you can use UNC paths and skip the fixed-size Unicode normalization buffer than introduces the `MAX_PATH` limitation: https://docs.microsoft.com/en-us/dotnet/standard/io/file-pat...
