VisualDiffer compares folders and files side-by-side using colors to visually show differences. From the Folder view it's possible to make operations on folders and files like copying or deleting. It's possible to compare directories quickly choosing base folders from the context menu. Using the File Filter feature, it is possible to hide specific files like .git, .svn directories, or the omnipresent .DS_Store files from visualization. Folder comparison can be done using different techniques from the fastest "compare only date and size," to the fine-grained byte-by-byte comparison. File comparison is done using the UNIX diff command. This choice makes the result quick, standard, and reliable. It's possible to save work sessions, then quickly reopen them to compare directories hierarchies or two specific files.
