Selecting a .txt file from different location

If i run the following code i can only select a file from the current working folder:

a1 = uigetfile('../Data/*.txt');

fid1 = fopen((a1), 'r');

c1 = textscan(fid1,'%d%f%s%s%d%d%f%d%d','delimiter', ';','HeaderLines',256);

g1=c1{2};

if i select a file from any other folder other than the working folder il get an error:

Error using textscan Invalid file identifier. Use fopen to generate a valid file identifier.

Error in samp1 (line 7) c1 = textscan(fid1,'%d%f%s%s%d%d%f%d%d','delimiter', ';','HeaderLines',256);

please let me know how to solve this

You could try this:

 [filename, pathname] = uigetfile('*.txt', 'Pick txt file','/Path/to/folder/Data/');

 a1 = fullfile(pathname,filename)
