gvim is a good tool for those familiar with the VI editor approach (think back to your days using unix terminals in college...if you were so lucky :) I think it can be found at gvim.org Someone here even posted a syntax highlight file to allow the various parts of the cr2 to show up in colors! My favorite is a program called ultraedit which does good job on large files (and can do all sorts of search & search / replaces across files and directories...I use it pretty much daily) Unfortunately, it costs a few dollars (but is really worth it if you edit text files a lot) eric
