How can I send text-files to a specific folders?

What lines of code would be useful to send .txt files to different and specific folders?

Here is my path.

H:\wall_location_dataset\ExtractVolume_01\avg DATA

My intentions is to send the 4 text files to avg DATA instead of ExtractVolume_01.

Here is a section of code of what I have for a set of codes. This part of the program allows the loop to assign a number to a text file (avg+j+.txt, ex. avg1.txt) and record slope and two y-intercepts. What approach should I use to specify the path to a folder (send to avg DATA) and allow the loop (for j=1:4) to assign the numbers to the textfile (avg[1,2,3, OR 4].txt?

fileOutput=sprintf('avg%01d.txt',j);

fileOut= fopen(fileOutput,'wt');

fprintf(fileOut,'Data avg results  \r\n');

fprintf(fileOut,'avg%0.0f\r\n',j);

fprintf(fileOut,'Data order (1-2): Slope , Y-int (xy1), Y-int (xy2) \r\n');

fprintf(fileOut,'Slope= %0.4f\r\n',m);

fprintf(fileOut,'Y-int(x1y1)= %0.4f\r\n', Bxy1);

fprintf(fileOut,'Y-int(x2y2)= %0.4f\r\n', Bxy2);

fclose(fileOut);

outdir = 'avg Data';    %you can fully qualify the directory name

fileOutput = fullfile( outdir, sprintf('avg%01d.txt',j) );
