Hello Jeremy, Paths tried (all from LOCAL - not http://) directory:
temp.txt (same dir as TW) ./temp.txt (same dir as TW) file:///g:/data/TW2014/temp.txt (same dir as TW) ../Business/papers/2015/test.txt (relative path to current TW) file:///g:/data/Business/papers/2015/test.txt (absolute path) All with text/plain. However, text/html does work. So maybe text/plain isn't supposed to work with canonical URI? I am using FIREFOX 33 with WINDOWS 7 and TW 5.1.8 Thanks!
