How to import data from a specific folder in MATLAB

Hi all,
I am trying to import a number of text files into my workspace so that I can do some data analysis and post-processing on them. The problem is these files are located in folders that are not in my current directory. I know I can change my directory or import them manually using the GUI but I would prefer to have some function that can import them immediately and that I can incorporate this function into my post-processing m-code.
I previously used something like this to import the files from the current directory:
clear all
files = dir('*.lvm');
for i=1:length(files);
eval(['load ' files(i).name ' R3F1T_']);
end
Maybe there is a way of modifying this simple code to allow me to import the same data from differnt folders?
Thanks in advance

filePattern = fullfile(yourFolder, '*.lvm');
files = dir(filePattern);
Then go read the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F for instructions and code examples on how to process files without using eval().

Thanks for the answer Image Analyst but still not working!
I tried implementing the code as following:
clear all;
filePattern=fullfile('C:','Users','Documents','Inlet Temp','*.lvm');
files=dir(filePattern);
for i=1:length(files);
eval(['load ' files(i).name ' R3F1T_']);
end
Keep getting an error stating:
??? Error using ==> load
Unable to read file R3F1T.lvm: No such file or directory.
Error in ==> test_load at 6
eval(['load ' files(i).name ' R3F1T_']);
Any more help/advice would be greatly appreciated. Seems like a small issue but is really bothering me!
