In my code, the user selects a file. That file name is assigned to "File1" as a char. Is there any way I can assign it as a string variable? I need to manipulate the name of the file after and need it in string form. Thanks.

    if true
      [File1,path] = uigetfile('*.txt');
if isequal(File1,0)
   disp('User selected Cancel');              
else
   disp(['User selected ', fullfile(path,File1)]);
end
    end

Is this what you're looking for? Or am I misunderstanding your question. And why do you need it as a string to manipulate it?

if true
   [File1,path] = uigetfile('*.txt');
   File1 = string(File1);
   if isequal(File1,0)
         disp('User selected Cancel');              
   else
         disp(['User selected ', fullfile(path,File1)]);
   end
end
