In the practice of Latex writing, it is common to use the same figure or figure directory across different projects (papers). Instead of a copy-paste-ing figure directory, which is usually big in size, it is better to just drop a line of latex code to specify where the location of the figure directory. By using this technique, we can avoid increasing memory size by preventing copying the same files/figures used by different tex files.
Here is how.
% for a single directory
\graphicspath{{figures/}} %Setting the graphicspath
% for multiple directories
\graphicspath{{figures1/}{figures2/}{figures3/}} %Setting the graphicspath
Don't forget the slash '/' after the name of the directory.
That's all. It works!
