Which wallet software is this file from

[pletharoe]

I found an old wallet file, but I'm not sure which wallet / vault software it was from, it has two files (.vault and .vault-journal)

Is there any way I can open it again?

After doing some googling it looks like the .vault files may be from a wallet called "mSigma", try downloading that and importing you vault files. I hope you find some btc on there, good luck

You could always open the file and see how the data is stored. Do you remember having a password for it? If so that might be a future problem if you don't remember it.

EDIT: mSigna is still avaliable to download as software from here: https://ciphrex.com/products/

If not, you could try to open the file in a text editor like notepad++ (as most data is stored in the following format):

Code:

TXs
{
    TX1
    TX2
    TX3
}
Addresses
{
    Address1
    Address2
    Address3
}
Private Keys
{
    PrivateKey1
    Privatekey2
    Privatekey3
}
(the private key part is the part you need).

It is an mSigna file for definite.  I have used this wallet for awhile and it is really good.  Maybe abit more of a commercial product tho rather than everyday use.  Think its developed by cipherx who have eric lombrozo in their ranks.
