windows - Problem with filestream path in C++ when copying files

Question

Brace with me here. I'm trying to make a few simple, but useful C++ console apps that I want to run by starting them straight from cmd (like DiskPart for example). I have a finished product, compiled by gcc through VS Code powershell. The idea is: I have a main.exe and a data file stored in "veco/data.txt" next to the executable. The code works perfectly well when started from its folder where it was compiled, but when I try to copy it to WindowsApps folder (to be able to start it by typing its name in cmd) it just doesn't work... Yes I did copy the folder too, I've tried to run it from powershell and I get 0 crash msgs...

Here's the part where I interact with the text file:

  string s = _pathToExe + "veco\data.txt";
  ifstream is(s);
  //i do stuff here
  is.close();

where _pathToExe is path to the executable, without the actual name of the executable. ifstream is(s) seems to be the crashing point.

I compiled the code using two commands:

g++ -c <all .cpps>
g++ -o main.exe <all objs>

Can I make this work somehow? Any other suggestions are welcome too.

Note: I've tried copying to other locations, doesn't work there either.
