I have two text files with 2.4M. I like to compare what are the differences in these two text files. I used Kompare. It worked but it is slow for a big file size. Looks like never finish the comparison.
What could be the best software in Ubuntu or Windows to compare and visualize the contents of two text files .
You should try diffuse
sudo apt-get install diffuse
diffuse file1 file2
