So I created a new folder, and am one-by-one duplicating the section files, moving it to the new folder, renaming the file <section>.tex copy (reps. <section>.ex.tex) as  <section>14.tex (resp. <section>14.ex.tex), changing the root to

I have the following weird situation: if I hit the "Typeset" tab from file dot14.ex.tex, the compiler works away on compiling the book until it gets to \input{dot14.ex} where it stops and gives me the error message: can't find file dot14.ex.  Same if I typeset from CalcThree14.tex.

Howdy,

Are all the \input commands in the root file or is the \input file for the exercises in the section file? If you ``typeset'' the section file does it go through? I also wonder why you didn't just duplicate the whole folder. Also, while it shouldn't make a difference, it is bad practice to use a period as part of the file name; something like <section>.tex and <section>X.tex would be better. Finally, you say you tried to change the file name, how about making sure the \input command is correct without extra characters.

Good Luck,
