I am trying to compare two trees with lots o' files with many different extensions. I only want to see the .c and .h files. I have selected Multi-file and recurse into subdirectories. In the filespecs field I have *.c; *.h. It doesn't find anything. It says "No Files match these parameters". I think because it doesn't want to recurse into the subdirectories because they don't match *.c and *.h. If I put just "*" in the filespecs then it works but I see everything in the world, which makes it very complicated to see what I am really looking for. Is there something else that I need to do to do recurse into subdirectories with filespecs of *.c; *.h ?? Thanks.
