This will not check if the file is truely a new file. If calling this with an existing archive file, it will overwrite the table of contents, corrupting the file.
public static CreateFile ( CustomFileStream stream, MemoryPool pool, int fileStructureBlockSize ) : DiskMedium
stream CustomFileStream An open to use. The /// will assume ownership of this .
pool GSF.IO.Unmanaged.MemoryPool the to allocate data from
fileStructureBlockSize int the block size of the file structure. Usually 4kb.
return DiskMedium

        {
            FileHeaderBlock header = FileHeaderBlock.CreateNew(fileStructureBlockSize, flags);

            BufferedFile disk = new BufferedFile(stream, pool, header, isNewFile: true);
