For developers and writers, it becomes important to keep track of the difference between files. Many a times you may need to find the difference between two different versions, different documents etc.
Here is a compilation of a few different tools/softwares available.
1) Diffchecker : Diffchecker is a tool that lets you compare the content of two files online. On a positive note, you don’t need to download any desktop software.On the flip side it can be only used for simple comparison of contents. You can’t compare the folders, directories etc
2) BeyondCompare: BeyondCompare is a tool that has richer set of functionality, You can compare folders, directories, files and also do file merge and folder synchronization. You can do text compare, picture compare , folder compare , executable compare, mp3 compare , registry compare and so on. It is a great product, it comes at a cost, a very nominal cost.
3) WinMerge: Winmerge is an open source tool that lets you do file and folder comparison and version control. The issue with winmerge is that its only available for windows platform i.e Windows 2000/XP/2003/Vista/2008/7/8/2012
4)Diffnow: Diffnow is an online tool that lets you find differences in two files, you can upload files to compare. There is another cool feature of this tool. It lets you compare two webpages. You just need to present the URLs of the pages to compare. But you may come across some annoying banners now and then for sure !!
