Yes, in fact, I do exactly this. It's kind of suboptimal, in that NSSavePanel will first give you a warning:
“Foo.oplx” already exists. Do you want to replace it?” and so on… the user will probably reflexively accept that one. Then we check and see that you're asking to dump a folder of web stuff, that the folder exists, that its contents don't look like a bucket of HTML and we pop up a second “That seems like a really bad idea, really really blow that away?” sheet. I think just giving this UTType a file extension is better than that experience, but having NSSavePanel properly maintain the extension (or lack thereof) would be better still. Though I could easily imagine having multiple export types whose Mime type is public.folder. -Tom On Jan 17, 2013, at 3:22 PM, Quincey Morris <quinceymor...@rivergatesoftware.com> wrote: > On Jan 17, 2013, at 14:12 , Thomas Bunch <t...@omnigroup.com> wrote: > >> Launch, take your "document" (very much a stub), File -> Export…, "My Flat >> Format".
