Set File Size

Musharraf_Hussain · May 9, 2011, 7:57am

Hi all,

We have minifilter driver to perform IO Operation on Virtual Drive FAT32 volume , We want to read all sectors of any file, either compete sectors filled by data or last sector has some data.

Example : Assume that Virtual drive FAT volume having 512 bytes per sector, file size is 524000 bytes, but it is filled in 1024 sectors (512 *1024) 524288 bytes,

I want to set file size upto 524288 bytes, because we want to send 524288 bytes of file to User Mode Application.

Thanks,
Musharraf

I don’t see a question here…Why are you trying to do this?

Hi,

Let me know Is there any possibility to read data all sectors of any file ?

Either last sector not completed filled or not.

Thanks

That still doesn’t answer my question…
