Windows File Explorer is many things. One thing it is not, however, is good at searching. It used to be… but somewhere along the way something got broken.
Fortunately, there’s a command-line tool that works much better than the GUI, called findstr. You can look up the options by typing
If you’re looking for a particular text string and you only want to know which files contain that string, use the following command:
findstr /S /I /M /C:TEXT_STRING_HERE *
The /S means search this directory and all subdirectories.
The /I means don’t be case-sensitive.
The /M means print only the filename if there’s a match.
The /C: specifies the text string you’re looking for.
The * means check everything.
