Potential error when compiling a folder path inside a GUI

Recently i have programmed a functional GUI, but in order to work it needs to change directory and use the information from an specified path folder. Now i need to turn this into an executable using the Compiler. I fear the code will not work since the path directs to a folder within the PC and the executable must run in other computers. Is there a way to include this foreign folder when compiling the GUI?

it has two ways:
1. either compile the .exe with the data in the folder 2. or ask the path input during compilation

So instead of accessing (for example)
data = xlsread('C:\Users\Edison\StarFire\TrainedData\Romulus\physcons.xlsx');
you would first move the file to be relative to the directory you are building the project in, making it something like,
data = xlsread('TrainedData\Romulus\physcons.xlsx');
and then you would convert that to something like,
romfilename = 'TrainedData\Romulus\physcons.xlsx';
if isdeployed
romfilename = fullfile(ctfroot(), romfilename);
end
data = xlsread(romfilename);
