xRecurseDiff
A developer tool to rapidly compare sources tree
...For every file in the first directory searches in the second for files having the same name. A report containing results is shown. A detailed diff output can be shown. Search can be case-insensitive and limited by a char filter.
In "library" working mode it compares only files basenames, while in "project" mode it compares relatives paths too. In "files" working mode it compares directly two files.
