Forgive me, but I've never been so frustrated by a program in my entire life. I've been trying to figure out how to convert a txt file to epub or mobi. I thought I just needed to click on the convert button, set the options and I would get the desired result. Where do the files go after being converted?? I clicked on the Jobs button, clicked to see the details because I couldn't find the converted book, and was pointed to I:\CalibrePortable\Data\settings\temp with several files named strangely. They were deleted once I closed the program in frustration.
Am I doing something incredibly stupid?

I've been reading the FAQ, this forum, and the
E-book Conversion instructions in the User Manual, but there's no simple step by step instruction that I could see. Where do I tell the program to save the converted ebook? I checked Preferences->Conversion, and tried a couple of profiles, left the defaults in since I don't have an ereader and tried a couple of profiles, finally returning everything to default because they didn't seem to work.
So, I'm once again asking that someone explain the conversion process as you would to a small child.
