I would be very careful of using ResEdit on your files. If you are not sure of what you are doing, you can totally destroy your file. Always work on a backup file. I use Word to open Cr2's on my Mac, but you have to set it to read all files or the Cr2 won't show up in your list. Word will open them as a text file. Be aware that Poser files are REALLY huge files. A 10 or 12 MB file will bring your text editor to its knees if you don't have enough memory assigned to it. Sorry, I don't know which free text editors can do this, since I've always had word. Diane
