uigetfile()

And

uigetdir

Also consider using appdesigner instead of GUIDE.

Thanks by help me, but I would like a function which I select the adress from past and the Current Folder from Matlab change

I discovered that function. It's "cd". Thanks by help me ;)

@Daniel Fonsêca: don't use cd: it slows down your code and makes debugging harder. Just use absolute/relative filenames, which are much more efficient. Just use fullfile like this:

D = 'directory where the files are';
F = fullfile(D,'name of the file.txt')
