WinMerge
About WinMerge
WinMerge is an open-source differencing and merging tool for Windows released under the GPL. It compares two or three text files or folders, presents the differences visually and lets you merge changes block by block.
Beyond text, it offers recursive folder comparison in a tree view, image comparison with highlighted or overlaid differences, CSV/TSV table comparison and archive support through 7-Zip. It can create patch files, help resolve conflict files, integrate with the Explorer context menu and serve as an external diff and merge tool for version control. Its interface is translated into many languages, including Simplified Chinese. It is completely free to use.
