File with .prv extension - is it private key?

[patoch77]

Hi,
I had Bitcoin wallet on XP. I belive it was bitcoin-qt. It was back in 2012 and since than I've changed system to win7, and lost most of files like passwords, backups...
The only file which I found recently is .prv file.
When changed to .txt it looks like this:

I've changed few letters in it to keep it safe  
but i'm not sure is any point in it....

Is it possible this is encrypted private key or something like that?

I haven't seen any Bitcoin software that uses files with a .prv extension, but there could be some.

Did you ever have Adobe Premiere Elements, or SoftMaker Presentations software installed on your computer? Both of those applications use files with .prv extensions.

Its possible... But I'm sure I wasn't using anything more than wallet app than.
So this is prv file is nothing usefull 
Thank you for help, anyway.

As far as I know Bitcoin core hasn't ever used files with a .prv extension, but other users here know far more about core than me, so I could be wrong.

It's worth keeping a copy of the file and continuing to ask for help from others. Is it possible you could have been using alternative wallet software to Bitcoin core like an SPV wallet?
