2015 BTC file……

So I found a file in an old external hard drive with some BTC I thought I lost. I have no clue how to restore it or access it. The file was a backup from an old android wallet file name Bitcoin-wallet-backup dated 02-22-2015. The file when I opened it up with word is 16 pages long. It’s been so long that outside of the above info I don’t recall much else. Any and all help with this is greatly appreciated
