How to compare two files and output the difference in Windows 7?

SpecialOne

I need a Windows tool which can compare 2 files in .txt format and output the difference. It should also work with large files. Example below:

Text1.txt

Apple 

Orange

Banana

Text2.txt

Apple

Orange

Banana

Lemon

Output.txt

Lemon

So how could I do this in Windows without using that "grep" tool which is Linux thing? I am also working with large files 100k rows. 

I tried this but it couldn't load my files properly: http://www.sobolsoft.com/comparetextline Also textmechanic.com doesn't seem to have this kind of tool.

Install 64 bit cygwin -> grep things -> profit.

OldFusser

ScrapeBox -> Select the URL list to compare

Thx both of you! I ended up using Scrapebox list to compare option, because don't have time learning cygwin. Problem is that I am comparing two files with text strings and are not URLs. Scrapebox is only accepting URLs when importing. Had to add suffix .com at the end of each line with textmechanic.com and then import them into Scrapebox. After comparing I had to remove .com sufix again. A lot of babysitting for simple task as this. Really weird that nobody came up with simple tool on Windows which can handle big files and we are in 21th century.

Donalds more right than Fusser. Though Fussers right to.

Learn Cygwin. You can google it, figure it out in 2-3 hours, and never look back.

Scrapebox can handle 1 million urls. Cygwin can handle.. well I dont know the limit, Lets say 900 million? It can also do the same job in seconds, rather than 45 minutes.

Thx all for your suggestions. Will definitely learn Cygwin, but now I don't have much time. For anybody looking similar solution my coder shared this PHP script for free: http://www.blackhatworld.com/blackhat-seo/php-perl/713950-share-compare-two-files-find-difference-php-script.html
