# Why won't Storage Studio touch a copy left behind by an earlier version or an update?

Storage Studio found what looks like an old copy left over from an earlier version or an update. It can see it but can't tell what's inside — and anything it can't check, it won't remove on your behalf.

If you recognise it and don't need it, you can remove it yourself in Finder.
