title: how to insert a folder of text files as an index inside arraylist?
body: <p>I was wondering if there is some way to insert some folder that contains some text files as an index in an arraylist, for example I created an arraylist named gestures, now I need to access some path that has 4 folders. For example folder up , folder down, folder left and folder right, each folder has some text files from accelerometer . what I want to do is to insert folder up with its data inside index 0 in the arraylist , folder down with its data in index 1 in arraylist and so on .. so is there some way to do this ?
  I am using windows form application C#</p>
  
  <p>in case points are not clear . 
  - i got some data from accelerometer saved in many text files.
  - and i got 4 folders "up,down,left and right" each folder has number of  text files with the data from the accelerometer .
  - what i want to do is to store the first folder named "up" which has number of text files which are data from accelerometer in index number "0" in the arraylist or a list and place the folder "down" in index number "1" in the arraylist or list and so on . in order to make some calculations on these data.</p>
