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) 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.

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.
