Connect a Time Capsule on iPadOS

iPadOS can access network drives that use the SMB file sharing protocol. The Time Capsule can be accessed by either the AFS or SMB (v1.0 only) protocols. I just tried this with my iPad Pro and it resulted in a "Operation not supported" error message. I believe this is because the connection attempt is with the newer (either 2.x or 3.x) version of SMB and the TC can only understand SMB 1.0.

I would second Bob's suggestion to try FileBrowser. Interestingly, you can "add" FileBrowser as a location type in the Files app ... and then, access the TC that way.

Not possible using an Apple application, but you might want to take a look at FileBrowser. A free trial is available. More info here:

I have no interest in FileBrowser other than that as a satisfied customer.
