Yes, it does. In fact, if you command click on the line \input 
{myfile.tex} of the main file, the pdf will open on the page  
corresponding to myfile.tex. Then, command-clicking on the pdf page  
takes you to myfile.tex. This makes navigation between multiple  
documents very convenient. Sometimes these synchronizations fail  
unpredictably but for the most part they work.

It is also possible to nest \includegraphics but this is a bit messy.  
It goes like this:

Root file:   folder0/folder1/main.tex
input file:  folder0/folder2/folder3/myfile.tex
graphics file:  folder0/folder2/folder3/mygraph.eps

In this example, folder2 is at the same level as folder1 and  may  
contain several problems in parallel subfolders, eg folder2/folder3,  
folder2/folder4, etc. I use this setup to keep track of homework  
problems by placing all associated files (graphs, notebooks, etc) in  
a separate folder for each problem.

To make graphics work, in myfile.tex load the graphics using:
    \includegraphics[scale=0.5]{folder3/mygraph}

In main.tex (root file) set the  graphics path to
    \graphicspath{{../folder2/}}

and load the source file using
    \input{../folder2/folder3/myfile.tex}

This should load the source file and the graphics. If the nesting of  
folders is different, one must make the corresponding changes.

The messy part is that the graphics path must be split into two  
parts, one that goes in  \graphicspath (this is the common part of  
the path of all graphics files) and the rest that goes in  
\includegraphics. This split is necessary if you want (as I do) to  
\input multiple files, each stored in different folders.
