Best way to interact with Gaia files uploaded/managed by now defunct applications?

Hey everyone, curious if you can offer any solutions for folks who are trying to interact with old files that were uploaded and managed files through a solution like pDrive, Rabbithole, etc. (Gen 1 apps, basically).

Because those apps are no longer maintained by their creators and are offline or broken, they cannot access their files the same way they did in the past. My understanding though, is that those files are still there and managed by the same wallet address/private key that they used with the app, they just need an interface through which to access it.

Is there a working app for this or a utility? Other pointers?
