Write/Read File in low level Program ?

how can I Write/Read file in low level directly into Disk, without using ReadFile /WriteFile.
I mean Read/write directly to Disk Sector.
what is Dos File Format, Window file format

Why do you not easily use the standard-c-library-functions ? :D

There is a set of functions inside that provides you with the possibility to write "old-school - low-level" file-access.

Look in your compiler help for the functions "open", "close", "read" and "write" or "fopen", "fclose", "fwrite" and "fread".

Have fun
