Stuck on deleting unwanted files Stop now or after current just keeps running.
I am not sure I want to delete any of my files. The source has not changed. These are archive files.
I don’t want it to delete my 3 TB of data, how do I stop it. Arghhhh…

Does this work for you? If so, please see if there’s an open [Issue](https://github.com/duplicati/duplicati/issues). If not, could you open an issue?
EDIT: On Windows, `.rpm` file won’t work easily, but there are also `.zip` versions of all the binaries.
