Title: I found wallet, but its format is not DAT, but XPT...

I found wallet, but its format is not DAT, but XPT...
I mined BTC around 2010, and then placed it for a long time. The hard disk has just been repaired. After reading and searching, I only found wallet xpt。 Excuse me, is this file a wallet file? Can you recommend me some tools to find the private key in the hard disk (with high security). I remember mining BTC in the mine pool. You can choose GPU mining and cpwu modes.

I tried to open wallet.xpt with a text editor, but it showed garbled characters. After using the code to open, display XXX XXXX XXXX XXXX XXXX. (1-9 A-F) Hexadecimal encoding. I created a wallet.dat. I tried to open it with this software and found it was the same encoding. But I changed WALLET.XPT to dat format, but BITCOIN CORE can't scan it. I started mining bitcoins with a computer in about 2010. I remember that I can choose to mine in two modes: gpu and cpu. When mining in gpu mode, the graphics card will make a lot of noise.
I am a computer novice and need detailed advice from everyone. If I can get my bitcoins back, I am willing to give 5-10% of the bitcoins in my wallet to the proposer.
Also, I tried to scan the hard drive with PYwallet, but PYwallet closed quickly after opening. How to solve it?

1. The file extension has a meaning only for the programs trying to access it.
2. All files can be seen as hexadecimal characters. The garbled characters tell it's a binary file, not a text. But that can be basically anything, from executable to database file or any binary data needed by an application, including wallet files.
3. A quick search on the internet tell that XPT extension may mean it was a Firefox plugin. https://www.reviversoft.com/en/file-extensions/xpt  Maybe it rings a bell.

Pretty sure that the wallet.xpt file is just part of Mozilla Firefox. I would be very surprised if this was in any way related to Bitcoin and/or Bitcoin Core.

If you open the file in a text editor and it starts with the text "XPCOM TypeLib" and then a bunch of "garbled characters", then it is 100% NOT a Bitcoin Core wallet file.

I have a feeling it has nothing to do with crypto/coins.
Probably one of Mozilla's product (maybe Thunderbird) so-called "wallet" for storing passwords. If you google for that, you will find lot of obsolete references to /components/wallet.xpt

pywallet? https://bitcointalk.org/index.php?topic=5301358.0
Before you start, I think you should do the raw copy/backup of disk, for safety.

I used search tool (https://ninjastic.space/search (https://ninjastic.space/search)) and found out there's 0 post which mention "XPT" in 2008-2010. Closest thing i found is x.pushthrough (XPT) protocol which used on some mining pool. But that protocol looks like only exist since 2013.

But I changed WALLET.XPT to dat format, but BITCOIN CORE can't scan it.

Renaming the extension actually doesn't change the format. So it's not surprising Bitcoin Core can't open/scan it.

Also, I tried to scan the hard drive with PYwallet, but PYwallet closed quickly after opening. How to solve it?

What command did you use? Did you see any warning or error message?
No, it just opened and closed quickly, so fast that I don't even know what happened.

OK, thank you. I will try to scan the hard disk with pywallet again. If I don't find the wallet, it will be regarded as my contribution to bitcoin combustion.
