I would like to use UIGETFILE function in order to search for any file from any path of my computer.

Hello everyone.

I am new to MatLab, and I would like to know how can I make the program be able to look for any file from any folder of my computer not just the MATLAB folder containing the program.

Currently I am using UIETFILE function and it works if the file is in the MATLAB folder, but if I write the following in the code:

[Archivo, Direccion]=uigetfile({'*.xlsx','Data Files (.xlsx)','*.*','All Files (*.*)'});

I get the following error:

Error using readmatrix (line 158)

Unable to find or open 'Curva_Produccion_Parque.xlsx'. Check the path and filename or file permissions.

Thanks for the help.

[Archivo, Direccion]=uigetfile({'*.xlsx','Data Files (.xlsx)','*.*','All Files (*.*)'});

if ~ischar(Archivo)
   return;  %user cancel
end

fullname = fullfile(Direction, Archivo);

data = readmatrix(fullname);

Hello.

I still get an error when (the error pops at the readmatrix function I have below) and it says the following:

-Full code:

[Archivo, Direccion]=uigetfile({'*.xlsx'},'Seleccione el archivo deseado');

DATOS=readmatrix(Archivo,'Sheet','Datos','Range','A1:C19','OutputType','string';

-Error:

Error using readmatrix (line 158)

Unable to find or open 'Curva_Produccion_Parque.xlsx'. Check the path and filename or file permissions.

@David Borrego: you are getting that error because you did not do what Rik showed you.

What you did (does not provide the path information to READMATRIX):

DATOS = readmatrix(Archivo,..)

What Walter Roberson showed you:

fullname = fullfile(Direction, Archivo);
data = readmatrix(fullname,..);

[David Borrego]

I get the exact same error I wrote on top.

For some reason, the readmatrix function is unable to find the file as I wrote

(Error using readmatrix (line 158) Unable to find or open 'Curva_Produccion_Parque.xlsx/Users/davidborga/Documents/TFG/TRAFO PARA PARQUE FOTOVOLTAICO/DOCUMENTACION INICIAL/'. Check the path and filename or file permissions)

And is clearly the readmatrix. I put a red button to stop and the prgram works until then and gives the correct answer for the fullname (Name+path) description as you can see:

>> MODO2

4 DATOS = readmatrix(fullname);

K>> fullname

fullname =

'Curva_Produccion_Parque.xlsx/-/Users/davidborga/Documents/TFG/TRAFO PARA PARQUE FOTOVOLTAICO/DOCUMENTACION INICIAL/'

[Stephen23]

"gives the correct answer for the fullname (Name+path) description as you can see:"

The error message clearly shows you have combined the filename and the filepath in the wrong order:

'Curva_Produccion_Parque.xlsx/-/Users/davidborga/... INICIAL/'
%^^^^^^^^^^^^^^^^^^^^^^^^^^^^                                   filename
%                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  filepath

All OS's in common use have the filename at the RHS end of the path (just as Walter Roberson showed you).

[David Borrego]

Indeed it was my mistake changing filepath for filename.

Thank you so much for your help (and sorry to Walter whose answer was perfect).
