Hi there, I wanted to ask this, and quite need your help. I have some confusion about why a certain document type (.rtf) takes a considerably long time, especially when compared to other documents (specifically of the .doc type). The documents in question here are .rtfs, around 250 megabytes, 209 megabytes -- in that range (some less); they contain a fair number of pictures. For an experiment, I tried saving one of the documents that took a long time to load (as .rtf) to a .doc, and then it loaded very quickly. Despite that, I'm asking here to also ask: what is the difference between .rtf and .doc? I don't want to change all of my picture-packed documents to .doc, and then they not be as safe. Thank you very much!
