I have already posted in https://stackoverflow.com/questions/26776003/how-to-use-htmldiff-in-django-to-show-difference-of-two-uploaded-files
However, I want to know if there is an easy way to upload a couple of files and submit which shows the differences between those two files in the next page. I made it work in the link above, but it won't work for large files like 4/ 5 MB.
I desperately need to solve this. Thank you.
Have you tried running a different diff tool on the server and just dumping the HTML output? diff2html comes to mind, maybe see this answer for some more details?
