hi, 
I have a problem to crete an executable using the command pyinstaller at the time of use the helper --onefile

I've created an executable using the next instruction:

pyinstaller --windowed --add-data "Rute PC to my Folder\Imagen";"Imagen"  Aplicacion_Calculadora.py  

The folder Imagen has an imagen that is called into the code and at this time everything work fine, the executable starts and works very fine. I have used the calculator and operations are correct and the imagen is upload in the interface, but I deleted everything and started again.

I would like to add everything in one File using the command:

pyinstaller --onefile --add-data "Rute PC to mi Folder\Imagen";"Imagen"  Aplicacion_Calculadora.py 

At this point, the executable never starts. If I saw the message in console when the .exe is running and it shows me the next error: 

File "tkinter\__init__.py", line 4061, in __init__
File "tkinter\__init__.py", line 4006, in __init__
_tkinter.TclError: couldn't open "./Imagen/Retroceder.png": no such file or directory [11320] Failed to execute script Aplicacion_Calculadora 

The executable never can find the folder and the imagen, it happenning just when I use the command --onefile

I've been looking in every documentation and instructions but I've not found anything about that error just using the command --onefile


May you help me with that error or what instruction I should add, please?

Attach code and folder with the imagen


Thanks
