S3Clients

Many popular S3 desktop clients can be used to access the UMIACS Object Store. These tools complement the UMobj command line utilities and the built-in web interface by providing integration with the native file explorer on your desktop machine.

Note: Many of these clients have features that are just not supported by our Object Stores in UMIACS. This includes permissions, which we suggest you manage permissions from the built-in web application for the Object Store.
