Be careful - if your account doesn't have permission to read any of the folders in the search path, the script will fail at the first one. In .NET Framework, there's no way to make a SearchOption.AllDirectories search skip folders you don't have access to.
If you're using .NET Core 2.1 or later (including .NET 5/6/7/...), you can use the EnumerationOptions[^] class with the IgnoreInacessible property set to true to resolve this:
EnumerationOptions options = new()
{
RecurseSubdirectories = true,
IgnoreInaccessible = true,
};
var files = DirInfo.EnumerateFiles(filePattern, options);

That's a great tip. thanks for adding.

I'm using Total Commander for that

Supports search by ANSI, ASCII, UTF8, UTF16, Office XML, EPUB, HEX and REGEX.

I've been using Agent Ransack for over 15 years and it's still a great piece of software for searching both by file name and within files.

Several 3rd party tools I keep available include "Windows Grep", grepWin and SearchMonkey. SearchMonkey and grepWin are my favorites. Both support regular expression searches.

GREP AND GREPWIN I HAVE USED BUT NOT WITHOUT ISSUES. SEARCH MONKEY i WILL TRY. I TRIED RANSACK. PRETTY GOOD.
WINDOWS DOES FINDSTR COMMAND BUT ONLY AT COMMAND PROMPT LEVEL. I KNOW THERE ARE MANY WAYS, MY ANGST IS THAT WINDOWS HAS NOT DONE THEIR OWN VERY WELL. I DON'T WANT TO HAVE TO THINK TOO MUCH EVERY TIME I USE IT. IT SHOULD BE INTUITIVE.

If you have Git for Windows installed already then you have the POSIX ports of grep and find for Windows already installed, it's just most likely they are not in your PATH to avoid name clashes. You can use it outside of Git Bash in CMD or PowerShell as it's just a Windows port.
C:\Program Files\Git\usr\bin\find.exe
C:\Program Files\Git\usr\bin\grep.exe
If you don't have Git for Windows installed, install it. No developer should be without Git these days.
Also, WSL2 is great, if you want to use a full-on environment. Better than the old Cygwin days. I say this as a dude that used to be all about PowerShell. If you're going to take the time to learn something may as well learn something cross platform that you can use on a Mac as well.

Personally, I download a copy of ripgrep and enjoy using the fastest, most concurrent text search utility you're going to find (at the moment, anyway).
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Not really my thing but with Windows 10 (before?) you can install a unix Bash shell. I think that comes with grep.

Today I finally got a NXP PCAL6534 34-bit GPIO expander working. I couldn't before. It wasn't showing up as an I2C device, even when I scanned the bus. I solved the problem, but the evaluation board is just funky.
Furthermore I just spent the last 4 hours (mostly) poring over a datasheet for because nobody wrote a driver for it, aside from one for linux which is actually weird considering it's not really meant for full fledged computers.
I got it working, and ported a stepper motor driver library to work with it, such that you can tie most of the motor's lines to the expander, and you only need one for each attached directly to the MCU (because it's time sensitive.)
All in about 4.5 hours today, which is over twice as long as I like to work in a day, but I had a lot to do. From what I understand of my pace, and just generally what I know of work like this is I did it very quickly so I feel pretty good about it, especially given it involved datasheets, which usually make me cross-eyed, and then the finicky and obscure hardware on top of it.
Why we didn't go with a more common expander I will probably never know. I'm not a hardware engineer.

You are even better than a hardware engineer.
You are a hardware/software engineer.
Pretty good one.
You have a bigger picture.
A good thing.

Why?
Because the marketing department wanted to say: “cutting edge technology using NXP PCAL6534 34-bit GPIO expander”

Funny thought, but I know that's not how this happened.
I know the guy that made the decision. I could ask him, but he probably just went with NXP because he's used to them, and this is what they had. He's not up on the software end of things, so the fact that NXP doesn't do a good job (apparently) of providing source code to work with their hardware is almost certainly lost on him.
It's not a big deal - if anything it means more work for me, and that's not always a bad thing - not when I'm already ahead anyway.
