Firstly, this should be:   \graphicspath{{FolderA/}{FolderB/}}

  a.  without the ,  which is redundant;
  b.  you need the directory delimiter /

otherwise LaTeX looks for   FolderAFile1.tex   or  FolderBFile1.tex
by simply prepending the tokens to create the name.

I'd expect it to be rejected out-of-hand.

The security reason is to prevent damage from running TeX on a file
sent to you by someone else --- or at least restricting any malicious
damage to the folder hierarchy below where the document has been

Your idea --- if it included paths with ../  --- would totally
negate this security aspect.

Besides, there is already the possibility that you desire.
Simply place your files within the ~/Library/texmf hierarchy,
e.g. within

Exactly the same search paths are used for any LaTeX input
construction, such as:


and also the TeX primitive  \openin .

There is a disadvantage to putting all of your files
into  ~/Library/texmf/....
It means that they can be found inadvertently by other
jobs, where you want to input a file having the same name.
Thus you'd really need to use unique names across all
the different projects that you manage.

The alternative is to structure your projects such that
you are always looking downwards within the directory
hierarchy for your  \include'd  files.
That way there'll be no restrictions on writing .aux files.

The use of (Unix) symbolic links to shorten paths has already
been mentioned. This is also a good trick --- but this may not
work if you share your files with someone using Windows.
