How many times do you find two or more versions of a single document in your computer? Did you use to program? If you do, this will sound familiar. Today, I’ll like to write about a terrific tool that will help you manage these documents.

WinMerge is an Open Source visual text file differencing and merging tool for Win32 platforms. It is highly useful for determing what has changed between project versions, and then merging changes between versions.

When you select two documents to be compared, you’ll get visual differencing and merging of text files. The documents are located in different panes so you can quickly see both.

For instance, if you download an open source application form the internet and then you make some modifications in the code, this application can quickly help you find those modifications comparing them with the original files. I use it also with office documents. It’s really cool!
