This worked against 335 PDF files in 180 directories when I ran it on my laptop. There are other ways to work from this code to do more elaborate renames but my main intention was to show how to use File.Move to do a batch rename. You can check and replace any character in the name you like or just specify a whole new name using replace functions. NOTE: In this example code we open a directory and search for PDF files with open and closed parenthesis in the name of the file. ![]()
