This software offers a solution to users who want to search for words or phrases within multiple files. First, drag and drop files you would like to search in or use the 'Add Files' buttons. You can also load a list of files in C:\test\1.txt C:\test\2.txt format as long as entries are separated by a line break. Next, simply enter a string of characters to find. You can filter results by clicking "Remove Results Containing X" or "Remove Results Not Containing X." The final results can be saved to a text file or copied to the clipboard for pasting.
