I would recommend you to use a scalar variable that contains the pathname till C:/abc/abc1/, use hash of arrays or hashes to have your IDs and folders like GS12345 and then use another scalar variable to concatenate the path+folder that you are interested in. I think that would not lead to memory issues. Also, searching would be bit faster.
