WinMerge is a free open-source file comparing/merging application designed for Windows, with which we can compare the contents of multiple documents or even the differences between folders. This is suitable for programmers or users who often need to write or modify codes or articles.

When you have two or more text files with similar content, WinMerge will come in handy immediately, to help you check the differences between these files. If you’ve ever written a program then will understand this situation: when modifying the program versions, we often need to know what is the difference exactly between the new program codes and the old ones, but this is indeed a problem that makes a person nerve-racking.

Or sometimes you maybe need to make line-editing and proofreading to two articles or more with slightly different content, but it is still quite tiring if you wanta check up from the starting, at this time, we’d better let WinMerge help us to realize that automatically.

WinMerge does comparison to the content of two files, and highlights the different ones, in order to make users check quickly, moreover, you can directly make the leftward file content cover to the right, and vice versa. This is quite convenient a feature for users who need to modify the contents of documents frequently.

Compared with the similar commercial software, such as Beyond Compare and UltraCompare, etc. WinMerge is perhaps not as powerful as them, but with its small size, portable, open-source and free benefits, I believe it will also obtain many users’ love.
