New here and first time posting here so I apologize if Im in the wrong section.

So I made a file back up onto a 2TB My Passport external hard drive using Windows 10 File History backup. I later renamed the folder to something other than the standard "FileHistory" windows names it. Thinking my files were just backed up I was happy and reinstalled a fresh copy of Windows 10 after formatting my partion for clean install, I noticed everyone of my files windows had added the Date/Time stamp to the original file name. Its very annoying having the time and date added to the file names. Is there any possible way to restore my files back from my Ex HD. Ive tried using the File History restore but it wont recognize the back up. Even after renaming the folder back to the default "FileHistory" the back upcreated before I renamed it?
