File system in vivado SDK

What does it do instead? Does it run? Does it report any kind of 
error? Do you at least get a valid filepointer?

Does your hardware support any kind of memory on which a file system 
can be implemented?

Ouch, ouch. Does your zynq hardware have a drive "c:\"?
As far as I see: you have a big problem about understandig where your 
software is running actually.
It is NOT running on your PC with your drive "C:\Users\...". Instead you 
develop software thats running on a zynq-board on your table without any 
drive "C:\Users\...".

Become clear about the design flow and the target. At the moment you are 
on the very wrong track!

HI
thanks for the reply. I am new to this area. I got a fair idea of what 
is happening. Basically i need to process a file of size 25MB. If i 
store that in a header file in vivado SDK, the compiler hangs. So i was 
exploring these options.

Do you have any idea regarding this.(I am using zed board (zynq 7000) 
for processing)

What kind of data is in the file? What kind of process must the FPGA 
perform?

Usually it goes like this: you read the file in the PC and send a 
datastream via Ethernet to the FPGA. The FPGA does some calculations and 
sends the result back to the PC. There you store it an the hard disk.

If you have the MicroZed at least, then you have a microSD port. And 
there should be some samples how to access it.

To be honest: I'm not that sure at all...
