Help removed apps left behind files

[dj.GETAFIX]

i have removed some apps but there is still some of the files on the sd card..
should i either delete the files with the pc or download the apps again then clear the app cache before removeing again???

will just deleteing the files with my pc when it hooks up to the htc cause any problems or fail to remove hidden files elswhere for the apps??

also could somebody list what the default files would be from a new phone and what the file
names mean/corespond to please so i dont delete important files

thanks
