but this command gives me error that file system 'ntfs' not found. I hv given ntfs in capitals also but error was same. tell me how can I access windows files on Linux
True. You're probably doing nothing wrong (it is not written in capitals, it's correct when written as 'ntfs'); it's just that the Fedora stock kernel, at least at the moment, does not include ntfs read support. You'll have to either find a kernel that has it built in/as a module, or recompile the kernel yourself to add ntfs support. Another option is something like Captive or Fuse (if I remember correctly) which work on i386 (not on 64-bit I suppose), and provide ntfs read+write support; the problem is just that their write support is bad (most of writing/deleting will fail) so I wouldn't count on them. Better just recompile the kernel, if Fedora doesn't provide a stock one with ntfs support built in.
I was also surprised to see that Fedora does not ship with ntfs support, because many other big distributions do.
