Shared drives are shared spaces where teams can easily store, search, and access their files anywhere, from any device.
Unlike files in My Drive, files in a shared drive belong to the team instead of an individual. Even if members leave, the files stay exactly where they are so your team can continue to share information and get work done.
This is especially relevant for retiring staff who may want to leave their files for their replacement or cohort.
