When to Use FileFlush() function ?

[Rickname]

Even by reading the Help file I still don't get it when exactly to apply this function, and what happens if I don't use it ? Thanks

FileFlush()

Every time you need to be sure that the data has been written to disk.

Let's say a "transaction" consists of 3 writes to a file. The "transaction" is fully processed when all data is being written do disk. That's when FileFlush is being needed.

You need FileFlush if you want full control over a file. But I think it is rearely used.
