| Spec score · Diff and Merge Tools | 8.1 (#12) | 7.0 (#26) |
| Folder comparison | It compares and merges directory trees and can synchronize folder hierarchies. | Folder comparisons can use regular-expression file filters, compare files by size and date, and include subfolders. |
| Integrations | The SourceGear DiffMerge manual lists integration instructions for Git, Mercurial, TortoiseSVN, Microsoft TFS, and Microsoft VSS 2005. | WinMerge offers Windows shell integration, archive support using 7-Zip, and plugin support. |
| Purpose | DiffMerge compares and synchronizes folders and compares and merges files. | WinMerge compares files and folders and presents differences visually for merging. |
| Support | The opened DiffMerge support page currently displays demo-site text rather than product support information. | The support page directs users to discussion forums and asks bug reporters to include the WinMerge version and, if possible, a configuration log. |
