Nope, not if you would use something like Ape, I think, if I read Shanes 
comment correctly:

But this doesn't expose enough, what you'd need would be something like 
an "external path", which could be the filesystem path in case of Ape or 
something more exotic when you are using other storages, which offer 
alternative ways to serve their data (oracle file system for instance).
Since this information is only known to the storage, but can be 
valuable, there should be a way to get it.
