file comparison and differencing tool
WinMerge 2011 is an Open Source visual text file differencing and merging tool. It is highly useful for determing what has changed between project versions, and then merging changes between versions. It features visual differencing and merging of text files, a flexible editor with syntax highlighting, line numbers and word-wrap and handles DOS, UNIX and MAC text file formats. It also includes full support for archives with the bundled 7-Zip plugin. The WinMerge 2011 branch is a continuation of the older WinMerge release.
