About WinMerge
WinMerge is an open source tool for comparing and merging files and folders on Windows. It shows differences in a visual text view that is easy to follow.
What it does
WinMerge compares two files or two folders and highlights the differences. Its editor shows line numbers, syntax coloring and word wrap, and differences inside a line are marked. It can also compare images and CSV or TSV tables, create patch files and resolve conflict files. Shell integration for Windows lets you start a comparison from Explorer.
