# Filesystem storage driver
An implementation of the `storagedriver.StorageDriver` interface which uses the local filesystem.
## Parameters
`rootdirectory`: (optional) The absolute path to a root directory tree in which
to store all registry files. The registry stores all its data here so make sure
there is adequate space available. Defaults to `/var/lib/registry`.
`maxthreads`: (optional) The maximum number of simultaneous blocking filesystem
operations permitted within the registry. Each operation spawns a new thread and
may cause thread exhaustion issues if many are done in parallel. Defaults to
`100`, and can be no lower than `25`.
