If you are working on the files in C#, then the extension is not hidden - it is only not displayed to the user in dialog boxes and windows explorer. As far as your code is concerned, it is there and readable.

how can you identify whether the file is .pdf or .doc if the extension of a file is hidden mode.
i am processing only .pdf files what i am doing is:-
i am reading the .pdf and i am processing
if the .pdf is hidden i can't able to read through the code...

It's only hidden from users: if you are using FileInfo objects to refer to your files (and if you aren't, do) then you could look at the Name property "myfile.pdf" or the Extension property ".pdf"
