old version -- leftover files

[fpefpe]

Hello -- I just installed the new version of dvdfab (9.1.9.6) and in created a new install directory "dvdfab 9 us" -- I had an older version that was installed in the folder "dvdfab 9" -- I UN-installed that version but it seems that all the folder "dvdfab 9" was not deleted -- and all its content

Is it save to delete the old install folder "dvdfab 9"

Thanks
