Somehow inconsistent isn't it?
You don't say what platform you're working on, but I'd guess Windows, because on Windows "inst/extdata/" (or "inst\extdata\") is not a valid path. The dir() function works around this issue by removing trailing slashes as appropriate, but unzip() passes the work to an external utility, and it is stricter about enforcing the rules of the platform.
