How to search for a particular file or all files from a graphical interface

Question

Is there some graphical tool to search for a particular file or all files of that format from a folder and many sub-folders and which takes a query like *.txt and the path of the partition on which the folder with many sub-folders is located and output the result?

Answer 1

Open Nautilus, the default file manager, by searching the dash for Files or clicking Files in the Launcher.

Press Ctrl+F

Type your search. You can chose whether to search in the Current folder or All Files. For just txt files, type txt. Not the wildcard (although it may work, I don't think it does).
