Java Heap Memory Error for processing large files

Question

While processing Large file i am getting Java Heap Memory error. I am developing tool which checks specified regex on each line/sheet from file. It works fine for below 2mb files but when i process large size files it gives error.

Application uses recursive function to loop on Files and folders.

Please help me with this, because i need to run it on multiple user system.
