PDOKAN_FILE_INFO FileInfo,
PDOKAN_OPERATIONS DokanOperations)

(PFILE_ALLOCATION_INFORMATION)((PCHAR)EventContext + EventContext->Operation.SetFile.BufferOffset);
// A file's allocation size and end-of-file position are independent of each other,
// with the following exception: The end-of-file position must always be less than
// or equal to the allocation size. If the allocation size is set to a value that
// is less than the end-of-file position, the end-of-file position is automatically
// adjusted to match the allocation size.

}
// How can we check the current end-of-file position?
