I tried purge-broken-files

I renamed all four files to include a prefix of old- ex. old-duplicati-bf426ae80110f43f1b0152b388060ec92.dblock.zip.aes and ran the purge-broken-files once more:

for some reason, it just worked on 2 files this time, not 4. I don’t know what to make of this and I don’t know if my backup is ok now…
