I found a thumb drive from a recently deceased sister-in-law, It has some files on it labeled Vault one two three and four. The only Vault files I know of are for Bitcoin. I have not found anything that will open these files. Any insight is appreciated!

Hey guys. My uncle is asking for my help he sent me a message which is this post’s title. I personally got into bitcoin only 5 years ago using modern apps so I’m not sure how to advise him on ancient cryptotech. Any tips and help is appreciated. No dms will be answered, please comment here. I’ll be searching to see if a vault keyword pops up in another already existing post.

Edit: I’m sorry to add to the suspense or fake news or etc. I removed the names and my uncle prob doesn’t Reddit so I asked here to see if any leads on that. I found another post that suggests to search for a wallet.dat. I sent him that instructions but I asked him if he has access to her old computer. I assume a flash drive is not standalone and that there’s another program to open those files. I also asked for clarification if there’s a .doc or .pdf etc what the file names were to see if I can get that cleared up from my uncle.
