xRecurseDiff is a small program that can rapidly traverse entire directory trees to show different version of the same files, for example to compare different version of the same project.
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.
