-   ReadFile and WriteFile functions in Windows have BUG:

-   If you Read or Write 64MB or more (probably min_failure_size = 64MB - 32KB + 1)

-   from/to Network file, it returns ERROR_NO_SYSTEM_RESOURCES

-   (Insufficient system resources exist to complete the requested service).

-   Probably in some version of Windows there are problems with other sizes:

-   for 32 MB (maybe also for 16 MB).

-   And message can be "Network connection was lost"
