Need help on recovering a deleted file on my company’s server.

Hi. I need help quick. Today, I just found out that one of my coworkers deleted all of my files on my account on the company’s server as a prank. I tried calling the IT or people with administrator accounts to help me but only the IT has that access. My company’s IT is on vacation. I need help. My files are really important. My computer is a workstation and is connected by a network into a central server. I don’t know how to undelete the files. If my boss finds out, he might fire me. Please. My coworker said he used the SHIFT+DELETE combo to delete all of the files. Please contact me at my email at rwong93@ymail.com

Thank You.
