Hi Andrew, as discussed earlyer, there is no hard coded limit in the size of the files (ok, you might not go over 2GB per file) Althought its usually not nessecary to edit such big files. Use inheritance, reuseable code and part your document into smaller pieces. This is what Zope is for. I can't split it up, but it _is_ the browser screwing around. I uploaded the file directly into zope and if I view it its ok, but attempting to edit it, the text area window is limited to 100k in IE 5 for macintosh. -andy
