[RESOLVED] HELP -> File I/O

[salehhamadeh]

Hi gurus,
I'm willing to create my own file system, which I will use for my external hard disk. Can anyone tell me how to read binary data from the hard disk and write to it. Thanks 4 help.

Are you joking?

Thanks for nothing, souldog.

I searched MSDN and used the WIN32 API CreateFile() to open the physical drive and the WIN32 API ReadFile() to store the data into a buffer.

That's not exactly creating your own file system though...
For your own FS, you would need to first come up with a physical storage method, including directories and allocations on disk, then write an Installable File System driver for Windows to use it.

Which is why I asked if you were joking.

I didn't want windows to use it, I just wanted my own explorer to use it.

you might want to consider using the C++ io streams for writing and reading binary files. They are easier to use than directly using the WIN32 API.

you would be using fstream with the flag std::ios::binary

I know how to use fstreams for handling files, but my problem is that I want to access a physical drive. Is there a way fstreams can access physical drives?
