I use an old program called "Visual Search and Replace." It's really old, because it comes with both DOS and Windows versions. (Windows 3, I suspect!) It sometimes has trouble with really long lines, but all in all, it works pretty well. I used it mainly for web page design. When I need to change my e-mail address every time it occurs, say, I can do it without having to remember every page I put it it on. Just set it to search all files ending in "*.htm," search all subdirectories, don't confirm changes, GO! I'm sure there must be something more up-to-date now. The ability to do this kind of bulk editing without opening the files is quite useful.
