I want to do the same sort of\nthing, but with a directory hierarchy.\n\nIf I say \"exclude *.jpg\" in my root .gitignore file, that applies into\nsub directories, so I just assumed \"exclude !*.jpg\" would also apply to\nsub directories.\n\nAm I missing another way to accomplish this?\n\nI understand from an implementation perspective, skipping all\nsubdirectories when you see \"exlude *\" is a smart thing to do, but\nperhaps it should only be done if there are no negative excludes that\ncould bring items back into play?\n\nThanks,\nStephen\n"}]}
