Seems I've run into a small dilemma. On a 'project' I've been working on I've been adding a number prefix to the filename (##. ), and to speed up the process and ensure uniformity, I've been using Magic File Renamer to do it automatically. However, I think I mistyped "," instead of "." in the filenames on some files. It wouldn't be an issue to go back and check them, but I'm dealing with 4,864 files and 771 folders -- and growing. Neither explorer's search nor command prompt return anything useful, they just list all files/folders.
