File recovery

[dellboy78]

Hi guys
GOt a quick question, probably easy for some of you. I recently deleted some files around 3 months ago, and have overwritten data in the folder since. I have since realised that there was a file that I need, but cant seem to recover it. Is it unlikely that I will ever recover this??
