Windows 11 has a search box in the upper right when you open File Explorer (it used to be called Windows Explorer). If you don’t see it there must be some option to make it visible which you have to set. I would go nuts if I didn’t have this, I use it all the time.
I appreciate it but I am afraid that I am one of those horrible Linux/FreeBSD users. Loved Windows 7 until they started messing with it but I do still miss the xplorer2 file manager and the volume shadow copy service that made making backups while programs were open possible. Used both DocFetcher and Recoll on Windows and just carried them over when I switched.
