UltraEdit is awesome. I just had to find and replace several text strings in files on a web server. I didn't have a clue about the exact location of the files. So, it seemed like one hell of a job.
UltraEdit came to the rescue. In the toolbar of UltraEdit, you can find the Search > Find In Files option. Here you can add the directories and subdirectories where UltraEdit has to do the search job and you can even use Unicode search and regular expressions.
